4.  Solving a Wireless Router Unreliability Problem

Last week's email newsletter article "Wireless Problems Solved with New Router" motivated subscriber Len to write about his own experience. He solved a router problem in an entirely different manner...

Hi Terry,

You may remember giving me advice on opening old *.WK3 files: I did it by using Win 2000 and the, converting to Excel format. Len couldn't handle the Lotus 1-2-3 files because Excel does not install the "filters" for Lotus' .wk3 files by default. Fortunately, you can install them later from the CDROM.

Your recent newsletter brought back the pain of my Linksys WRT54GS, that even after updating to the latest driver, still kept loosing it's marbles and refusing to connect.

In the end I decided to open the case and look for a battery or capacitor that may have been faulty. There were none, but two chips directly under the two hot spots on the case.

I decided that with nothing to loose, I put two rows of 3/16" holes 1" from the bottom at the rear and two 2" square matrix of the same above the location of the chips. The greater number of holes at the top to encourage a flow of air over the chips. Not pretty, but effective!

This completely solved the problems.

Regards

Len

Cool! (pun intended!)

Most of us know that heat is the enemy of electronics. An overheating CPU will make the computer shut itself down, and can even kill the CPU.

That's why we need buy a can of compressed air occasionally, open our computer case, and blow the dust out of the CPU's heat sink. A CPU fan, if it is set to blow into the heat sink, can pack the dust between the cooling fins of the heat sink.

You really don'e want to disassemble the heatsink from the CPU — and that's the only wafe way to use a brush to clean the heat sink. That's why you can find the cans of compressed air among the computer supplies at your favorite office supply store.

Len's solution to increase the air flow through his router is doing the same thing — he's not installing a fan, and it's not a dust issue, but he's making sure that some cooling air can cool the hot chips of the router.

5.  My Computer Security Software Recommendations

I review my security software recommendations and update them for each weekly newsletter issue, if I think they need to change.

My Philosophy: Many people want to pick their most economical solution and prefer an all-in-one anti-virus, anti-spyware and firewall solution. In concept, that's a great idea. In actual practice, I don' think that this type of package is likely to be the best in all the protection categories you need.

Other people want to pick the best of each type program. I'm one of the these folks.

My choice of software that I am willing to recommend is driven by my search for software for me to use. I only recommend programs that I like and that I use. I will sometimes suggest alternatives to my recommendations, but I clearly note if I no longer use them.

Anti-Virus

I'm often asked about several other popular anti-virus or anti-virus combination packages. Yes, I realize that they are not in my recommendation list. "Enough said..."

From 2003 through mid-2008, my personal choice was ESET's small, fast NOD32 anti-virus program, which offers a FREE 30-day evaluation license. I still consider NOD32 to be one of the best in anti-virus protection — and it continues to get recognition and awards. Unlike some of its competitors, ESET offers multiple-year licenses also, and includes program updates in the multiple-year license.

However, I've changed from my long-time choices NOD32 (antivirus) and Sunbelt's CounterSpy (antispyware) to Sunbelt's new VIPRE Antivirus + Antispyware.

I've found that VIPRE puts even less load on my computer than the speedy combination of NOD32 and CounterSpy. I've also been impressed with the way its "deep scan" has found and eliminated risks that were stored in zip files, which is one of the latest malware email tricks. Sunbelt Software offers multi-year licenses and home site licenses on its software, both of which include program updates as well as signature updates.

My anti-virus and anti-spyware choice for my computers and those of my family's computers is VIPRE Antivirus + Antispyware

I'm often asked for alternatives to the programs that I recommend, especially by people who want to buy one package (a "suite") to do everything.

As a result, I tried a couple security suites in the last few months to pick a suite to recommend. ESET Smart Security 4 is my recommended suite alternative. Smart Security 4 has gotten great ratings and includes antivirus and antispyware, both from their current NOD32 v4 version, and antispam and firewall. I no longer use it and have returned to Sunbelt's VIPRE, but for a suite choice, that's what I would use.

Firewall Software

While the Windows XP firewall is much better than no firewall at all, but don't count on the Windows XP firewall to meet your needs.

You need a two-way firewall, which the Windows XP firewall is not!. Microsoft woke up and supplied a two-way firewall with Windows Vista. However, Microsoft built in pre-authorization for many programs. Windows 7's firewall is also two-way, and again has pre-cleared many programs to communicate outbound to the Internet — some to go where you want to go, and some to "call home."

The Windows XP firewall does not control outbound communications originating from your computer — and you should want to have control if adware/trojans/spyware or even commercial products want to talk to the Internet. Whether they are calling home or spewing spam, you want to be able to control your computer.

Do you want Windows Media Player to call home every time you play something? It does! Do you use the Search function in Windows Explorer to find things on your hard drive? Did you know that every time you search, Windows Explorer talks to Microsoft?

I didn't know that when I ran ZoneAlarm, but the Sunbelt Personal Firewall flagged that to me, and I can stop it or allow it to happen. Many other programs try to call home when you run them, too.

I recommend my choice for a firewall program, which is Sunbelt Personal Firewall.

You can try the full-featured "paid version" of Sunbelt Personal Firewall free for 30 days — after that, you can register it or, if you're using it on a home non-business computer, you can let it revert to the free, lesser-function license.
Tip: Be sure to read my review of SPF for the settings I recommend.

At this time, the Sunbelt Personal Firewall works with Windows 2000, Windows XP and Windows Vista, in 32-bit versions only. Recently, Sunbelt announced that SPF should be available for 64-bit computers in the first quarter of 2010, including Windows 7 support. I can't wait.

Sunbelt Personal Firewall is regularly $19.95 (with discounts for multiple computers and/or multiple years!) for a non-expiring license for the program and includes one year of their updates subscription. A unlimited Home Site License is $39.95 for a year.

Anti-Spyware / Anti-Adware Software

CounterSpy, from Sunbelt Software, has received many kudos from the computer press for its always-running and periodic full system scans. It has been my personal choice for my PC's and my family's PC's.

Sunbelt's CounterSpy v2.5, both improved CounterSpy's performance against malware and reduced its impact on system resources and responsiveness when its scanning.

Sunbelt continues to release updated program versions — the current version is v3.1 — and there's an even newer version about to be released. Nicely, Sunbelt do NOT install the updated programs automatically. You have to use the Update process in the program, which means that you'll know that something significant has changed.

I changed from my long-time programs NOD32 (antivirus) and CounterSpy (antispyware) to Sunbelt's VIPRE Antivirus + Antispyware.

I've found that VIPRE puts even less load on my computer than the speedy combination of NOD32 and CounterSpy. My computer seems to have much more pep and power than it had previously. I've also been impressed with the way its "deep scan" has found and eliminated risks that were stored in zip files, which is one of the latest malware email tricks.

Anti-spam Software

In today's Internet world, the question is not "if" you will get spam, but "how much will you get?"

I use and recommend POPFile as my first choice for handling spam. POPFile sits on your computer, between your email program and your ISP mailbox, and handles emial as it downloads.

POPFile uses a different approach to handle spam than some other programs do — it does nothing to reduce spam. It is designed as an email classification tool — you train it to recognize spam and any other type of email that you want to classify. These classifications can help you sort your emails into appropriate folders in your email program.

Sunbelt Software, who makes the anti-spyware program CounterSpy (which I use and recommend) and the firewall that I use and recommend (Sunbelt Personal Firewall) also has a well-regarded, award-winning anti-spam program called iHateSpam for Outlook and Outlook Express. Since I don't use Outlook or Outlook Express for email, I haven't tried iHateSpam.

Mailwasher Pro would be my first choice to handle spam before it ever gets into your computer's Inbox. Mailwasher Pro uses on-line Realtime Black Lists mail servers sending spam recently, "training" by you of what you think is spam, and your own "friends" and "blacklist" lists. Note: I found that PopFile generally meets my needs and stopped using Mailwasher Pro, even though PopFile works AFTER the emails have been downloaded. If I used a dialup connection, I would be more interested in Mailwasher Pro.

Mailwasher Pro can even bounce spam messages, as if your email address was not valid, although the usefulness and appropriateness of this is questionable. There is a free version called "Mailwasher," but it omits the functions that I consider critical for this purpose -- such as safely previewing the emails safely before they ever get to your email inbox.

Backup Software

When we think of security software, we usually think of antivirus, firewall, antispyware and antispam software. But, what other kind of software is security software? Backup software, of course.

We need to make backup copies of our important data. That data may be financial, such as your checkbook in Quicken, or your spreadsheet tracking your investmants. Or, it may be personal, non-financial data such as digital family photos.

What if your hard drive won't start one day? What will you lose? What if your computer is stolen (let's ignore, for now, whether you should encrypt data on your hard drive to protect it from others — let's just think about the inconvenience and loss to us!)?

There are two basic types of backups you should do.

You need to regularly back up your individual data files to another computer, to an external hard drive, or even to an online repository (but realize, if you have to rebuild the data on your computer, it may have to be downloaded for days and days). An external hard drive is the best choice if you don't have a home network where you could copy to another computer.

If you have a home network, use Karen's Replicator (free for personal, non-business use) to back up the files that change. I have it scheduled to copy my data files every evening from my notebook to another computer at my home. You should also get an external hard drive (or two, so you can alternate them) and make occasional backup copies to it. Preferably store it at a relative's house or your safe deposit box.

If you don't have a home network, get an external hard drive (or two, so you can alternate them) and make regularly scheduled backup copies to it. Use Karen's Replicator (free for personal, non-business use) to back up the files that change to your external drive. Preferably, store one external drive at a relative's house or your safe deposit box, so that if the worst happens, you haven't lost irreplaceable photos and other information.

The other type of backup is an image backup. This gives the ultimate in quick restore capability. Just plug in the external drive, boot the cdrom, and restore the image back to your hard drive. I use Acronis True Image Home 2009 (they also have discounts for upgrades)to make backups across my network every three days. Once a month, I make a full backup image. Every three days, it makes an incremental backup — copying only those files that have changed.

Acronis True Image Home 2009 (and later) allow you to recover individual files and folders from the image files, so you don't have to restore everything. The nice thing about making my backup across the network is that I can restore individual files across the network from those images. Sometimes that's the easiest thing to do.

Why Replicator and Acronis True Image Home, if we can restore individual files from both? Replicator will always have the latest version it backed up — but not any earlier ones. With Acronis True Image, we can have multiple versions of the files to choose among. We can restore one that's months old, if we like, and not just the latest version.

Cable/DSL Router

If you have a cable modem or a DSL modem, you need to have another layer of inexpensive protection between you and the Internet. A cable/DSL router isolates your computer from direct connection to the Internet. Your computer can easily request your email, web pages, etc. through the router. The responses come back to the router and are smoothly routed to your computer. But, someone on the Internet side of the router can not initiate a connection to your computer — they can only respond to your request.

Even if you only have one computer to connect to your cable or DSL modem, I recommend that you purchase and use a cable/DSL router because of the protection it can give you against attempts to attack through some flaws in Windows itself.

A router isolates your local network, whether it is only one computer or several, from the Internet by actually making it a separate network. The router gets the "public" IP address and handles all your outbound communications and the responses to them. But, it blocks computers on the Internet side from being able to initiate communications with your computer! This will prevent you from falling prey to many worms that try to attack security holes in Windows itself.

For a wireless router, I still recommend the Linksys WRT54G wireless router. When the "n" specifications become final, I'll recommend an "n" router. Even though the specs have been through so many drafts, I still remember the fiasco of the dialup modems built on the draft specifications — and then the final specs were not quite compatible...

If you don't want wireless, I recommend the Linksys BEFSR41 wired router, which I also use. Either way, based on my experience, I recommend Linksys routers for price, reliability and Linksys' habit of releasing updated firmware for their products..
