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.

How to get rid of the Vundo (Virtumonde) trojan?

Q.

Hi, recently my computer started acting weird. Some of the icons on my desktop were different (white paper icons?) when I tried to click the programs they wouldn’t work. I did a scan with (norton antivirus) but got nothing. I still suspected something here, so the only thing I could think of was a system restore. Although my icons came back, many of my originally installed programs (hp media programs) were there but could not work when I clicked them! I had to reinstall programs like mixcraft, because it was corrupt. I searched to find what was it that was making the software impossible to run, and the only thing that I have found for now is the Vundo Trojan, and so far nothing is working for me… I tried FixVundo.exe, I’m not sure how to manually delete it from the registry (I’m not really sure how to get rid of it at all), but so far nothing works, and I’m a complete nooby, and worried my new laptop will just crash on me. I have an hp envy 14, windows 7, and I’m in dire need to get rid of this dreaded pest! Thank you!

A.

Ahh, Vundo (or, Virtumonde)… It’s been around for a long time, in a variety of “mutations”, but the song remains the same. Vundo is a pain to remove, but it is possible.

First, you’ll need to download a few things.

If you have any networked computers (other PC’s connected together), you’ll need to run through this list on all of them – this spyware/virus can infect shared folders on networks.

You already have a Vundo remover, but just to make sure it’s the correct one, download it here.

Download this one as well.

Download CCleaner.

Download SuperAntiSpyware (cheesy name, I know, but it works).

Finally, download SpyBot Search and Destroy.

Now for the fun part. As an Administrator (not a limited user), install ALL these programs, then update them. Get a cup of coffee, it’s going to take a while. When you install them, right-click on each file and select “run as administrator”. This should make the programs available to each user on the PC. And yes, you have to run the programs under each user.

Now that the installs and updating are done, go in to your Control Panel and disable System Restore. This needs to be done as Vundo / Virtumonde often hides in the System Restore directory, which can’t be effectively scanned by virus and spyware scanners.

Next, restart the computer in safemode / without networking. While the computer is rebooting, keep tapping the F8 key, you’ll get a menu. Safe mode, without networking. Once Windows starts, log in as the same user you installed all the software as.

First, run CCleaner, checking in every checkbox except Wipe Free Space. This will take some time as CCleaner removes all the temporary files from the computer (removes some of the virus, and makes further scanning faster).

Next, run both the Vundo removers.

After that, run SpyBot, then SuperAntiSpyware. Both will take some time to run.

After they are done running, log out, and log in as any other users and re-run Spybot and SuperAntiSpyware.

You’ll need to do this on any other computers that are connected to this one (laptops included). All PC’s on the same network could possibly be infected.

After all is said and done, Vundo should be completely gone. Make sure to turn System Restore back on, and you can remove the installed programs if you wish.

In the future, make sure you have a good AnitVirus / AntiSpyware program running, because whatever you have now either dosn’t work, or is in need of updating. AVG Internet Security does a good job of stopping these kinds of threats, and isn’t horribly expensive.

Last but not least, don’t click on anything, EVER, that says “click here to scan your PC” or “click here to make your PC faster” if it comes up in a web browser – your web browser will never tell you that your computer is “infected” and offer to fix it – hence, a Trojan.

Happy hunting!

Windows 98 PC quit working, Missing Operating System

Q.

A friend of mine has an old Windows 98 PC, and for the most part it has worked good, played movies and videos, etc.. Today I turned it on, and it says “Missing Operating System”. I’ve never seen this before, and it has worked fine for a while now, even last night they were using it, but now I’ve tried 3 times and it just says “Missing Operating System”. Is there any way I can manually boot this up? What is going on?

A.

There are a few possibilities, but the most likely problems are either a hard drive that has gone bad, a hard drive cable that has come loose, a BIOS that has lost it’s settings, or the OS got wiped out somehow (either by user error or a virus).

The first thing to check is the BIOS. You need to make sure the hard drive is set up correctly. A Windows 98 PC would likely have an “auto-detect” featurein the BIOS to set up the drive.

If that’s not the case, check the cable going to the drive – open the case (usually a few screws) and look for a long, wide grey or black cable (it will have about 40 wires bundled together, about 2” wide) and make sure it’s securely plugged into the hard drive and the motherboard.

If that doesn’t solve the problem, chances are (being a 13 year old hard drive) the hard drive has failed. Not much you can do but replace it (Newegg.com still sells IDE hard drives for cheap), and reinstall the OS.

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 are the most common (and least expensive) inkjet printer cartridges?

Q.

I’m looking to stock my office with some new, cheap inkjet printers. I’m just wondering which inks are the most plentiful (and therefore cheap). I’ll be using both HP and Lexmark printers, if that helps.

A.

HP and Lexmark inkjet printers and inks are probably the most common, found in almost every Walmart, Sams Club, Best Buy, and other big-box stores. The most common inks in use are:

——————-123inkjets————

HP:
# 61 (Most current HP Inkjet Printers)
#’s 17 (Color) and 27 (Black), which are high yield, older inks.
#’s 16 (Color) and 26 (Black), which are normal yield, older inks.

LexMark:
#’s 14 (Black) and 15 (Color), most new Lexmark InkJets
#’s 36 (Black) and 37 (Color), most new Lexmark InkJets

These inks can all be found at local retailers, either OEM (original manufacturer), or generic / remanufactured.

I for one have never had any problems with reman’d inks, so long as the come from a reputable source. Ordering ink online is ALWAYS the cheapest way to go, as the retail markup on ink is outrageous.

I’ve tried many online vendors, but the best for quality, price, and delivery time, in my opinion, is 123inkjets.com. They’ve always got some deal going on, and shipping is free if you purchase enough ink. They carry ink for everything, so give them a shot.

How do I send a text from my computer to a cell phone?

Q.

How can I text a cell phone from my computer without using my data included in my cellphone service?

A.

For almost every make of phone, you can use Yahoo Messenger to send texts to cell phones. You don’t need to install YIM on the computer, you just need a Yahoo ID (free), then you can use Yahoo’s Web IM and send messages to a cell phone number.

Streaming NetFlix on TV from PC

Q.

If I have a USB male to male cable and have it run from my PC tower to
my TV, will I be able to stream NetFlix through it?

A.

The USB port on most televisions is used for mass storage purposes, I.E. to view movies or pictures stored on the USB storage device (flash drive, external hard drive, etc.), and won’t be able to be used for streaming purposes. A simpler solution would be to buy a video / audio cable setup for the PC and connect it to one of the television’s auxiliary ports.

Can’t decide between an eReader or a Tablet

Q.

I really want an Internet device that I can use in school. I need an eReader and Internet device. Which one is better? And which kind should I get. Is the Kindle good? I’m only willing to spend about $150 max.

A.

Given the versatility, I would go with a tablet, preferable something running Android. There are many available in the sub-$200 range. They have all the advantages of eBook readers, plus better screen resolution, better Internet browsers, and the ability to install more apps.

HELP! My computer keyboard isn’t working right.

Q.

For all the people who think this is a joke asking this question on a computer, YOU’RE WRONG! There is such thing as another computer which I’m using right now… The Keys that are working are… ty[]\ asdfghjkl;’ zxcvbnm,./ and the shift key, enter key, tab key, caps lock key, and the number don’t work except for 5 and 8 PLEASE HELP!!!

A.

Either the wiring in the keyboard is shorted, the connector has a broken pin, or the controller chip in the keyboard has gone south. Buy a new keyboard. Newegg.com has great deals on them, and they deliver fast. With the shipping, should cost about $20. I would suggest a Microsoft or Logitech keyboard, as they tend to last forever.
