1.  Broadband Problems and Questions

Sponsored Advertisement

This week, I received two interesting questions from U.K. subscribers. I wrote about and answered the other one, which was about external hard drives, in this week's email newsletter.

In this question, subscriber Robin wrote about problems she is having with her broadband connection...

Hi Terry

I have a stand alone desktop computer with a Tiscali.co.uk 8mb broadband connection and Windows XP Home edition.

Whenever I make or receive a telephone call, it cuts off my broadband connection. Any ideas on what could be causing this? I am using a Speedtouch 330 modem to connect.

Also, even though my broadband connection is supposed to be 8mb, it is not very fast and the download speed varies between 1mb and 3 mb.

I have been told that if I use a router, my broadband speed will be faster. I see you recommend routers in your newsletter but I am not very clear on routers. As I only have one computer, I don't see the need for wireless but I have been told that all wireless routers can be switched off and used as a wired router. Is this true?

Lastly, if I use a router, do I still need a modem to connect my broadband or will the router do this?

I am a subscriber to your newsletter and hope you can advise me on these problems. Regards
Robin

First, I'm not familiar with that brand of modem. Since Robin's broadband connection is getting cut off when she receives a telephone call, I assume she has a DSL connection of some type. With DSL, her broadband connection and her telephone connection use the same wires, but are at different frequencies. Therefore, she should not be losing the broadband connection when she gets a telephone call.

I browsed to the www.tiscali.co.uk site (which came up VERY slowly from this side of the Atlantic). I see that they sell the 330 modem for £19.98. However, Robin's may be an older verion of the modem.

I suspect her modem is the problem. She should talk to the Tech Support at her Internet Service Provider (ISP), who should be able to advise her on what to do. If she own the modem, I expect that they'll tell her to replace it. If she rents or leases the modem as part of her Tiscali service, they'll probably replace it.

Regarding her slow speed of the connection, it could be the firmware in the modem, or just slow speed from Tiscali. Also, it could be a tuning issue with her Windows TCP/IP settings. There are general rules on how to adjust Windows TCP/IP settings to optimize them for your particular situation. Alternativesly, you can use programs that are designed to apply the generalized settings for you. I used Optimize 2.0 to optimize my TCP/IP settings based on my particular circumstances.

In the U.S., the speed is always stated by the ISP's along with the magic words "up to" — as in "up to 8 Mb/second."

I strongly recommend that anyone using broadband also use a router. It provides a firewall of sorts — computers on the Wide Area Network (WAN) side of the router can talk to the router and the router talks to your computer. The router is the only device that actually has an IP address that is on the Internet.

Basically, your computer on the "Local Area Network" (LAN) side of the router requests a web page. That request gets passed to the router, which gets the response. Then, the router passes the response back to your computer on the "Local Area Network" side of the router.

Notice that I said "response" — the router will only pass responses to requests through from the WAN side of the router to the LAN side of the router. Any attempts to connect to your computer from other computers on the Internet get stopped at the router.

Robin also asked about turning off the wireless function in a wireless router. I don't know about being able to turn off the wireless functions on ALL wireless routers, at least now, but my first wireless router was one by Belkin — and it did not have the ability to turn off the wireless. Be sure you get one where you can turn off the wireless or get one that is wired only.

A router does not replace a modem. It is an addition to a modem. Some DSL (phone-line-based) broadband Internet service providers supply a modem that has a built-in router. Tiscali sells a combination modem-router. Personally, I would choose a router as a separate product, so that if I needed to update firmware or if it fried from a lightning storm or in some other way failed, I haven't lost both my modem and my router. I have a similar philosophy with regard to the printer/fax/copier combination models, televisions with built-in DVD players or video tape players, etc.

3.  My Computer Security Software Recommendations

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..."

My personal choice is the ESET's small, fast NOD32 anti-virus program, which offers a FREE 30-day evaluation license. I consider NOD32 to be the cream of the crop in anti-virus protection. Unlike some of the others, ESET offers multiple-year licenses also, including updates to the program in the multiple-year license.

Many antivirus programs will offer you an anti-virus signature subscription renewal when your subscription renews. I strongly recommend against this option — buy the full program or make sure you get program updates with the subscription renewal (like NOD32 does). Vendors routinely improve the capabilities and speed of the programs, too.

If you update only the signatures, you miss any program improvements. Fortunately, NOD32's subscriptions include both program updates and signature updates.

Firewall Software

While the Windows XP firewall is much better than no firewall at all, 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.

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 flags 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.

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.

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 is also my personal choice for my PC's and my family's PC's.

Sunbelt released their CounterSpy v2 in February 2007 and I promptly updated my computers to it. Version 2 greatly improved CounterSpy's performance and reduced its load on the computer when it was scanning.

In July, 2007, Sunbelt released v2.5 of CounterSpy, which again 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. Nicely, they 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!

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 now I 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 is 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.

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.

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 recommend the Linksys WRT54G wireless router. I'm using the relatively new version 6 of this router.

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