How to reset and secure my wireless router?

Q.

I was wondering if you could please help me!

I was trying to configure my wireless settings so that they are secure for all of my computers. However, I completely messed everything up! I don’t remember exactly what I did…just that I need a REDO button! I am able to connect wirelessly from my desktop computer, however, when trying to connect from my laptop, it says that it is unable to connect. I think the settings on my laptop have been messed up…and maybe it would be better to just reinstall the router?? My “dlink” connection is available but it will not let me connect. I was wondering if you could please help me.

My router is a DIR-615

The only thing I remember about what I did was that it printed the following when I tried changing things so my network was secure:

Wireless Settings
Network Name (SSID): Wagner
Network Key (WEP/WPA Key): ***********
Key Provided Automatically (802.1x): 0
Network Authentication Type: WPAPSK
Data Encryption Type: TKIP
Connection Type: ESS

A.

On the back of the router will be a small reset button, usually recessed into the plastic.  Using a paper clip, a pen, or something similar, depress the button for a full 30 seconds.  This will reset the router to it’s factory default.

As far as the D-Link software goes, if it were me, I’d uninstall it from the computer(s).  You do not need the D-Link software to access the router’s configuration, you just need to enter it’s IP address (usually 192.168.1.1 or 192.268.2.1) in a web browser.

As far as security goes – there is no such thing as a “secure” wireless connection, but there are steps you can take to make it very hard to crack.  Most important is using WPA for the encryption, and making the password as long as you can, using “special” characters (things like -’><}{][|\)(*&^%$#@!, etc…) – this will make it extremely hard for someone to crack. In your example (which I blanked out with *’s), you were using all numbers for the Network Key. NEVER use all letters or all numbers for a password with wireless – it makes it simple to crack. ALWAYS use a mix (something like “!a1^b2^c3!”).

Hope that helps.

Hosting for my web application

Q. (#1)

Hello, I am about to launch a website that is application based, and I am expecting some serious traffic on it. Can you tell me what a good hosting company for this? Thanks a lot and have a great day!

Q. (#2)

Hello guys I have one question about web hostings. I want to make a blog and I need a hosting for it, I can pay up to 8$ a month and I need a lot of space and of course high bandwidth. I’ll use wordpress for blogging. Can u suggest me one? Up to now, I’m thinking about http://a-host.net , godaddy, justhost.com and fatcow.com?!

A.

There are almost as many web hosting companies as there are websites. Most are fairly reliable these days, due to improved hardware. Personally, I usually use Globe Domain. The have all the stuff you’d need for hosting just about anything, and their price-per-bandwidth rates are really good. They’re also quick on problem resolution (customer support). One of my favorite aspects is that they are located in the US. Check them out here.

What’s the best way to link two computers to one modem, without using a router?

Q.

My brother works at home and uses a VPN and needs to be directly plugged into the modem, making the router useless. This sucks cause that means I can’t use the Internet while he’s working. Is there any two ported modems or anyway to both use the Internet at the same time?

A.

The router is not useless, it just needs to be set up with port-forwarding to direct the VPN traffic directly to his PC. If he’s using VPN, I would assume there is some type of tech support at his company that should be able to give him the information required to set this up.

If not, another option is using an Ethernet switch – it’s the Internet equivalent of a phone line splitter. As long as the modem supports DHCP (which most residential Cable and DSL modems do), this will work just as well.

Review: Broadband Satellite Internet Providers

In this day and age, it’s almost impossible to perform day to day activities without having broadband internet access. Unfortunately, not everyone in the US has access to cable internet, DSL, FIOS, or wireless internet. Dialup access is available anywhere you can get a dial tone, but lets face it, in todays internet world, dialup is dead – it’s almost impossible to navigate web sites these days with dialup, especially if there is any Flash or Java content. And streaming audio or video with dialup is just plain impossible.

If you’re one of the unlucky few who doesn’t have internet access via infrastructure systems (Cable, DSL, FIOS, etc..), your only alternative may be Satellite Internet.

Satellite Internet is what I like to call “not the best way to get broadband, but possibly the only way to get broadband”. Many rural areas in the US have no other options.

In the US, there are (now) three main providers for satellite internet – HughesNet (formerly DirecWay), WildBlue, and StarBand. One thing they all certainly have in common is their “cryptic” billing practices. Installation fees, equipment fees, lease fees, overage fees, early termination fees, the list goes on and on. It’s hard to decipher from their websites exactly what charges are involved, and their sales people are very well versed in the practice of disinformation. You could talk with a satellite provider’s representative for an hour and never get a “clear” picture of the actual costs.

Because of all this confusion, I’ve decided to make a simple spreadsheet that lays out the actual costs incurred in the installation and use of a satellite internet connection. The spreadsheet can be downloaded by clicking the links below – one is in .XLS format (Microsoft Excel) and the other is in .ODS format (OpenOffice and many others).

Basically, in my humble opinion, HughesNet is probably the best choice for the average internet user based on their low installation fee and many tiers of service. WildBlue comes in second for an average user, but is probably a better choice for those that tend to download more (videos, music, etc..). StarBand is listed mostly for reference, as they are more expensive, have less in the way of tech support, and in my experience, are generally less reliable than the other two.

There are some important things any prospective satellite internet user should be aware of -

First, you’re getting internet via a small satellite dish, which means bad weather can cause problems. Not so bad as television, as TV is an on-all-the-time deal, where any interruption is noticeable – internet disruption is less noticeable to the end-user. Generally speaking, all but the worst weather (mostly storms producing lightning or hail) won’t cause much of a problem with satellite internet.

Second, due to transmission speed and latency (the time it takes for an internet request to travel from your location to a satellite, back to a ground station, then the return trip), certain internet related services won’t work very well, if at all. They include VOIP Telephone Service, VPN Networking, online gaming in real time (First Person Shooters especially), and in general Video Conferencing, and anything else depending on a constant, steady exchange of data.

Third, satellite internet and heavy downloading don’t mix. Watching videos, using torrents or other downloading applications, downloading music, or anything else that is bandwidth intensive will violate a satellite providers “fair use” policies, or worse, will cause you expensive overages. Each provider (and each plan) only gives you a certain amount of daily or monthly download allowance – go over it, and your connection will get “throttled” (slowed down), or you’ll be charged exorbitant overage charges, or both. Careful monitoring of bandwidth use is a necessary evil (though the provider will alert you when you’re reaching the limit).

Keeping these points in mind, satellite internet is a fine alternative to dialup in areas where infrastructure broadband isn’t available. Hopefully this information helps you in deciding if satellite internet is right for you.

How to get wireless signal from Verizon USB modem?

Q.
I have a Verizon USB modem. I’m trying to get a wireless signal so that I can get online with my Ipod touch. Unfortunately, the modem I have isn’t a router and doesn’t transmit wireless. I believe all I would have to do is purchase a router to get my internet to pass it’s signal through. However, I’m not technologically savvy by no means and am wondering if someone can just tell me how I could go about getting wireless in my home by using my existing internet. Thanks!


Wirefly - FREE Wireless Internet Cards

A.
Unfortunetly, you can’t directly share the Verizon USB modem (or any other cellular 3G or 4G USB modem) via a router. There is however a solution.

The Verizon USB Cellular Modem is made to allow one computer to have access to the internet via cellular 3G. What you need to do is make the computer share the internet connection. This will require the computer to be ON in order to share the connection.

The computer will need a wireless card, or you’ll need a wireless access point or router. In Windows, you can share an internet connection via Internet Connection Sharing (ICS). ICS basically shares an incoming connection to other network devices through either the wireless card or ethernet port (then to an access point or router).

Instructions for setting up ICS can be found on Microsoft’s website for Windows 98 through Windows XP. Windows Vista and Windows 7 are a little more tricky – for those with a wireless card, you’ll be bridging a connection to the wireless (and creating an Ad-Hoc network), or bridging the connection to the ethernet port, then out to the AP / Router.

It’s not as hard as it may sound, but if you’re not the “techie” type, you might want to enlist the help of a friend who is familiar with setting up a network connection in Windows.

Looking for just VOIP, something simple, not a “package”, that works for a small business?

Q.
I run a small business out of a converted out building about 1000′ from my house, and I need a VOIP solution that will work with my wireless internet connection. I’ve tried using MagicJack, and while one works OK over the wireless connection, two or more causes major headaches or just plain stops working. I also tried a company called ViaTalk, but the quality of the calls was terrible. My wireless connection is to the house and is run off cable internet with a static address. I need at least 4 lines, and need it to work, and hopefully not cost much (less than what the phone company would charge for 4 additional lines, which is a TON of money). Any Ideas?

A.

Editorial Note – This answer is specific to a remote solution for business use, but the same equipment and providers would work equally as well for a single line residential setup.

VOIP (Voice Over Internet Protocol) is actually ideal for your low-cost needs, though 4 lines over a wireless internet connection is asking a lot. It’s doable, it just requires proper setup and equipment. The same setup will work just as well (or better) if the connection is wired.

In this case, the first thing you’ll need is a decent wireless router. The best choice based on experience is the Linksys WRT610N ver.2, running the freely available DD-WRT firmware. The extra memory and build quality of the Linksys combined with the stability of the DD-WRT firmware make for an excellent, low latency, highly configurable router setup. The router is to be used as the “internet connection” in the out-building, via the DD-WRT’s “bridge” mode.

Next, you’ll need a fairly capable wireless access point to connect to the cable modem, to provide a wireless link to the Linksys 610N. After some searching on the net, the best, most cost effective solution would be the TRENDnet TEW-637AP. It’s reviews show it to be a capable performer while having very few drawbacks. The 802.11n link between the two should be very reliable at 1000′, so long as there is a fairly good line of sight, which, if you can get a link right now, should present no problem.

Now that the hardware is sorted out, you’ll need a VOIP provider that can suit your needs. Four lines shouldn’t be a problem with the above hardware setup, so the real concern now will be cost vs. quality. After doing some research, it’s a toss up between two companies, depending on whether you want to use the VOIP virtually (through a PC), or physically (through actual phones).

For a virtual setup, RingCentral would be the way to go. You can get single lines, virtual fax extensions, even a virtual PBX (multiple lines), all at really good monthly rates (very competitive with other VOIP providers). They even have free trials on the single lines, so you could try the system out for 30 days to test it to make sure it meets your needs.

For a physically connected phone setup (utilizing separate phones for each VOIP system), the best solution for your business would likely be Nextiva. They have an unlimited phone service for under $17 per month (per line), and experience shows that you can in fact use several of their VOIP adapters at once over a single internet connection.

Your internet connection will have to support at least 128k upload per active line in order for everything to work properly, not including the requirements for regular internet traffic. For the 4 line example, simultaneous use of all lines would require 512k of upload capability. For safety’s sake, doubling that would be advisable (in this case, a 1MB upload cap should be sufficient).

Which is the best Antivirus Software for a PC?

Q.
I have a few PC’s at home and a bunch at work, and I (and my boss) can’t decide which antivirus is the best. Some of the PC’s are Windows XP, some are Vista, and a few are new Windows 7 PC’s. They also need antispyware software. Which is the best for stopping virus’s and spyware?


AVG Internet Security - Tough on threats.

A.
This is a question that we get a lot. And it’s complicated – the mix of home and business use, different operating systems, and the need for multiple installations presents a challenge. We like challenges :)

First, you have to understand, from a technicians point of view, spyware, virus’s, crapware, malware – all the same. It’s all software designed to either rip you off or use your computer to rip someone else off, all the while slowing down the PC, killing your internet speed, and causing pop-ups and other annoyances.

Finding an Internet Security Suite that works, but doesn’t slow the PC down horribly bad is a balancing act – more protection requires more processing. The best antivirus / antispyware software is that which is designed to protect the computer without using to many resources.

Asking which is the best is like asking which doctor is the best to rid you of an exotic disease. The answer is the one with the most (specific) experience. This translates to an Internet Security Suite that updates often. Unfortunately, this means more use of resources. Always a trade off.

By far, the most useful Internet Security Suite I’ve ever come across is AVG Internet Security ( Single PC / Multiple PC’s ). It has a VERY high rate of detection (though none is perfect) and protection, as well as a reasonable price, especially in a volume license setting (multiple computers), and works on Windows XP, Vista, and Windows 7. We’ve used it for a few years with great results. It’s also nice that AVG has a money-back guarantee for 30 days – if it doesn’t work, just return it, it’s that simple.

An important note –

Many times (most actually), someone will decide to purchase a new Internet Security Suite AFTER a PC is infected. The thinking is that it will somehow fix the pre-existing problems. The sad fact is, it rarely works that way. It’s like trying to put a patch in a tire after it’s been completely blown out – it just doesn’t work that way. In order for an antivirus or antispyware suite to be effective, it has to be installed on a “clean” computer. This may require bringing the PC to a qualified repair shop to either rid the PC of the virus’s (using another “clean” computer), or to backup the important information and reinstall Windows.

Another important note – most people believe in the logic of “if one is good, two must be better” when it comes to antivirus software. Not so. If anything will slow down a PC, it’s running multiple Internet Security softwares. They will constantly compete with each other, causing the PC to slow to a crawl. Only install one Internet Security Suite, period.

The best protection however, is the user. Certain rules should ALWAYS be followed when it comes to internet use. Rule #1 – nothing in life is free – especially on the internet. “Free” screen savers, security programs, downloaders, games, etc.. are almost always bundled with spyware or virus’s. Rule # 2 – if it ain’t broke, don’t fix it. Lots of times, a crappy website will pop up telling you your computer is infected, or your computer is “slow” and can be fixed by installing something. NO SECURITY SOFTWARE WILL EVER ALERT YOU OF PROBLEMS IN A BROWSER WINDOW! It’s a trick. Rule # 3 – if it seems too good to be true, it is. Clicking on an ad that tells you you’re a “winner” of some prize is almost sure to cause problems. Simple rules, but they’ll save you from hours of headaches later.

What is a good router for multiple computers and a PS3?

Q.
My router sucks! I want to be able to play PS3 without lagging. I want a router where I can be on the computer or laptop and on the PS3 without the connection being interrupted. What would be a good router for this?

A.
Using multiple connected devices will cause any router to lag a little, but a cheap router will definitely have more of an issue. What you need is a decent router that has QoS abilities.

QoS (Quality of Service) is just a fancy way of saying “load balancing” – making sure no single device gets priority over the others. QoS can also be tailored to give a specific device priority over others.

Most Linksys routers are capable of decent QoS on their own, it’s simply a matter of setting it up properly. The best solution though, in my opinion, is using a router with the DD-WRT firmware.

DD-WRT is free, and can turn an off-the-shelf router into a workhorse router. You can check out their site to see which router models will support DD-WRT. Personally, I’ve had the best luck with the Linksys WRT610N.

Another option that might work (or might not, depends on what router you have) is to put the PS3′s IP address in the router’s DMZ. You’ll have to look at the documentation for your router to see if it supports DMZ (most do).

Review: The COBY 7″ Mobile Internet Device (Tablet)

Tablets are a wonderful invention. They are especially useful when paired with a wireless network – hence Mobile Internet Device. School and college students, professionals who want more computing than their smartphones can muster, kids on long car rides (especially with a mobile 3G or 4G hotspot), you name it – tablets are useful to everyone in some way.

Some mechanics use them for diagnostics and for storing repair information. Network engineers love tablets for testing and documenting. Personally, I like them for their size and battery life (better in both respects than a netbook).

Well, like everything else, they cost money. Luckily, for what they’re capable of, it’s not much money. $200 is less than a new netbook, and less than the “other” tablets available, and just as useful. You just won’t get a fruity logo on the back.

COBY 7in. Mobile Internet Device

COBY 7in. Mobile Internet Device


Many of you probably have some COBY products already – they make DVD players, stereos, and the like. Their new 7″ MID is pretty impressive for the $180 price tag.

The Coby tablet features a 7″ color LCD screen with intuitive touchscreen controls. It can connect to your HDTV (HDMI) so you can enjoy TV in full 1080p. With the tablet you can play music, videos, view photos, text, browse the Web, and check your eMail. It also features a document viewer, alarm clock, calculator, and more. It runs the Android 2.1 Operating System on an 800Mhz CPU, is expandable from the included 4GB up to 16GB, a sports a WVGA (800×480) touchscreen.

I would have liked to see a higher resolution on the 7″ touchscreen, but 800×480 isn’t really that bad for something so small. Most web sites (and all mobile web sites) display just fine.

The integrated wireless (802.11g) works fairly well, keeping at full strength about 100′ from a standard WRT54G router. After 100′ though, it starts dropping off quickly.

All in all, for under $200, the COBY 7″ Mobile Internet Device is a great deal, especially for those on the go all the time.
