Not your password for Windows — you may or may not change that, based on your personal preference (or if at work, based on the requirements of your employer’s network).

I’m talking about changing your passwords on your wireless routers and wired routers.

Whether you use a Linksys router, a DLink router, a Belkin route, or one of the many other brands of routers , whether you use wireless or regular Ethernet connnections with your router, change the password from the default password — now!

In my security articles on routers, I have long recommended that you change the router’s password. Sure, it can’t be accessed from the Internet side of the router, but if you manage to pick up some automated malware or a trojan that gives remote control of your computer to someone else, you may find your router subverted. It may run all of your requests through their system, so they can log and analyze your actions, passwords, etc.

Well, the automated malware that I’ve long predicted has now been found in the wild.

Switching to WPA2 Wireless Encryption

October 19, 2008 By

OK, after reading Improving Your Wireless Security about WPA2 wireless encryption, you’ve downloaded the WPA2 encryption patch for Windows XP — or you’ve installed XP Service Pack 3, which includes the patch.

How do you switch to it? It’s easy.

First, we need to get to the router to make the change there. The procedure will vary by brand, but should be fairly obvious. The steps are to:

1. Use your web browser to log into your router
2. Select the Wireless Security settings tab
On the Linksys WRT54G, that’s Wireless < Wireless Security
3. Now, change the Security mode to WPA2 Personal (the name varies by manufacturer —

Improving Your Wireless Security

October 16, 2008 By

If you’ve read some of my other articles about having an open, unsecured wireless network versus securing your wireless network so that others can not get into it, you know that I believe in security.

I recommend that everyone secure their wireless network to the extent possible. It’s impossible to completely secure a wireless system, but you can block out most users. You can make it difficult for others to use your network.

The point is to make the process hard enough that the visitor — the unauthorized person who is trying to use your network for normal Internet usage or illegal and/or immoral actions — decides to use someone else’s network.

Windows XP Screen Freezing

October 13, 2008 By

Reader Steve Sturgill wrote to ask about screen freeze problems he was having:

Mr. Stockdale, My OS is XP, my ISP is MSN and I connect through broadband. My problem is, any time I right click, as in attempting to access dropdown menus, my screen freezes. Also I am unable to click on any of the tools in the top, left corner of my screen – i.e. File, Edit, View, etc. This has been going on for several weeks! I have looked extensively for a solution online – to no avail. Several sites suggest using a program called ShellExView, which I downloaded and tried, several times, in vain. Nothing seems to work. Can you please advise me? Any and all suggestions would be greatly appreciated. Thanks very much, in advance, Steve

I wrote back to Steve to suggest some actions to try to resolve his problems.

I’ve seen some strange effects like that before – not those exactly (except the apparent freezing on right-clicking for a context menu).

More Windows XP SP3 Woes

October 7, 2008 By

Reader Tom Linton wrote about is problems that occurred when he installed Windows XP Service Pack 3 shortly after it was released:


Terry,

I made the mistake of not being patient. SP3 had been out about a week and I hadn’t seen very much in the various email newsletters I subscribe to. A few friends had told me they installed SP3 and had no troubles. One even commented that his PC ran noticeably faster after the upgrade. So, I went ahead and upgraded 2 of my 3 PCs. Bad timing!

My primary PC (a Gateway GM5045H) did not appreciate the medicine, my secondary PC (my hand me down to my wife, a DELL Dimension 8200) upgraded with no know problems, and my third PC is to old to run XP.

My Gateway refused to run I.E.7, crashed my Media Center, would not let me connect to the Internet, and generally ran very slow. There may have been other problems I didn’t wait around to find out about. I did research (which I should have done before the SP3 upgrade, but I trusted MS to get this right since it was so long coming) with my wifes PC. The consensus was to uninstall SP3. I did this. My Media Center worked again but I.E.7 refused. I uninstalled I.E.7 back to I.E.6. It seemed to work OK. I upgraded to I.E.7 and it crashed again. Back to I.E.6. I only use I.E. for those pages that will not run properly in Firefox.

My real problem is my personal LAN. All the other PCs can see my main PC but my main PC cannot see them. Network Magic could not resolve the problem. I have searched the Internet and tried several suggestions on various forums. None have restored my ability to see my other PC’s on my LAN. I cannot PING the other PC’s. It is like the SP3 upgrade changed some settings to tighten up LAN security, but I cannot find how to undo them.

Any suggestions?

Thanks,

Tom,

Tom said that he could not ping the the other computers from his computer. — by name – or by ip address? If you can’t by IP address, then something is blocking them. If you can ping by IP address but not by name, you would know that it’s Windows name resolution that is causing the problem.

Windows XP Service Pack 3 Woes

October 5, 2008 By

So far, I’ve still avoided installing the new Windows XP Service Pack 3. I know that a lot of people have installed it without any problems.

However, when there is a problem, it is not trivial! Recently, two subscribers wrote to tell me of their horror stories and ask for suggestions on solving them.

Delmer Tergarden wrote to say that he had installed Windows Service Pack SP3 and the drivers for both the CD and DVD drives stopped working. Even though he restored the system to its state just before back up, his CD and DVD drives still were not recognized by Windows. He wanted to know how to get the drives working again.

I wrote back to say:

I haven’t installed XP SP3 yet, to avoid running into any of the early-adapter problems like you did. That’s why I think Microsoft made a blunder in its choice to push SP3 as a high-importance update as its initial release. It really abuses our trust of the update system.

Anyway, …
