Gigabit Ethernet Didn’t Make Internet Faster
Reader asks why upgrading to Gigabit Ethernet didn’t improve their Web surfing speed.
Q: I recently purchased a Linksys WRT 310 wireless router that has four Gigabit ports. My Dell desktop is a XPS which I was told was “Top of the Line” has a built-in gigabit port. I even purchased new cables to make sure my network was going to be “gigabit”. I hooked it all up and I don’t see any improvement in my internet. The salesman told me that “gigabit” was the fastest.. so how come I’m not surfing faster? Did I do something wrong or do I need to buy a different brand? Thanx.
A: No, you (most likely) didn’t do anything “wrong”, and you don’t need to buy a different router.
Let me, first of all, cover a few “basics” (see also, Wired or Wireless?*)
Kilo = 1,000 = thousand
Mega = 1,000,000 = million
Giga = 1,000,000,000 = billion
And then let me ask you to look at a simple network diagram.
In this diagram, the Internet is represented by the “cloud” (thus.. “cloud computing”) and I made it appropriately dark and stormy. The Internet connection is represented as the yellow zigzag — this can be a phone line (dial-up, DSL, IDSN) or a coaxial cable.
The blue is your (now Gigabit) Ethernet cabling.
For sake of argument, I made the Internet connection a cable High-speed connection, and I made the download speed a Premium-grade 12 Mbps .. 12 “megabits” per second. (I’d like to have this in RL.. but I have 3 Mbps DSL).
Note that I said “download speed”. Unless you order a special line into your home/office, your “Internet speed” is always your download speed. And, your “upload” speeds are always significantly slower.. as represented by the 486 kilobits per second.
The lines you changed are the blue lines. And so, yes, you have billion-bit lines there (Gigabit). You have multiplied by a thousand the theoretical rate at which computers A, B, and C can “talk” to the router and to each other. You did not change how the modem and the cloud are talking. That is still 12 Megabits down/point 486 (.486) Megabytes up.
Your Internet speed is controlled by two things: one, your service “level” (3 Mbps is more expensive than 1.5, and 6 Mbps is even more expensive, etc.) and two, the technology that can come into your home — dial-up, DSL, ISDN, Satellite, cable, wireless, and fibre-optic.
Because your desktop can “talk” to the router at a higher rate of bits, you might notice a very slight improvement in surfing speed.. but, if you want faster Internet, you have to upgrade either your service level, or/and the method it comes in on (the yellow zigzag) .. say, upgrading from dial-up to cable.
The advantage to Gigabit Ethernet comes in when transferring data across the LAN.. say, from computer A to computer B. Such as if you are backing up the files on A over to B, or “streaming” videos from C to A and B.
The Linksys is a good router (though I read that it runs hot, so you want to keep it in an open, well-ventilated area) and all-Gigabit on your LAN is a “good thing”.
I just think you were expecting the wrong results.

A Vast Criminal Enterprise Aimed At You
– Five Defensive Strategies
“Today’s Internet attacks are organized and designed to steal information and resources¹ from consumers and corporations. The web is now the primary route by which cybercriminals infect computers. Cybercriminals are planting malicious code on innocent websites. This code then simply lies in wait and silently infects visiting computers.
The scale of this global criminal operation has reached such proportions that Sophos discovers one new infected webpage every 4.5 seconds – 24 hours a day, 365 days a year. In addition, SophosLabs, our global network of threat analysis centers, is sent some 20,000 new samples of suspect code² every single day.
2008 at a glance
- Biggest malware threats – SQL injection attacks against (legitimate) websites and the rise of scareware (aka “rogue” anti-malware programs)
- New web infections – one new infected webpage discovered by Sophos every 4.5 seconds (24/7 x 365)
- Malicious email attachments – five times more at the end of 2008 than at the beginning
- Spam-related webpages – one new webpage discovered by Sophos every 15 seconds
- New scareware websites – five identified every day
- Top malware-hosting country – US with 37 percent
- Top spam-relaying continent – Asia with 36.6 percent
- Amount of business email that is spam – 97 percent
Injection attack? By exploiting poorly secured legitimate websites, hackers have been able to implant malicious code onto them, which then attempts to infect every visitor. One of the reasons the web is so popular is that legitimate websites can attract large numbers of visitors, all of whom are a potential victim.
(This as also known as “poisoning”.)
Many well known organizations and brands have fallen victim to this kind of attack during 2008. Both large and small organizations have been targeted.
January 2008: Thousands of websites belonging to Fortune 500 companies, government agencies and schools/universities were infected with malicious code. more..”
¹ read “money”
² read “malware”
Folks, this is taken from a whitepaper titled “Security Threat Report 2009” and produced by the IT Security firm Sophos. Some of the emphasis is mine. You can download the document here.
I want to take a moment to thank them for publishing this, and saluting their effort to combat malware and the criminals behind it. In fact, let me go a step further and salute all you whitehats out there. Thank you.
What you can do
1: please read Top 10 things you should do to your computer–updated. It is a checklist, and provides you with the How To’s for a (more) secure computer, as well as providing links to important (free) security downloads.
2: enable an anti-phishing filter, which can help alert you to poisoned websites before you go there. All modern browsers have a filter built in, and all you have to do is turn it on; or, you can add a toolbar/plug-in such as McAfee’s Site Advisor or the excellent WOT.
3: make sure ALL the programs on your computer are patched and up-to-date. The easiest and most effective way to do this (IMHO) is to download and install the PSI (Personal Software Inspector) from Secunia.
4: Never respond to e-mails asking for personal information. Legitimate businesses never contact you about “important issues” via e-mail. But criminals love to go phishing!
5: Be PARANOID on the Internet. (Use common sense) Think someone can’t trace back to you? Guess again; your browser reveals a wealth of information by default. Sound too good to be true? It is. There’s no such thing as a “free iPod”… and, no, you did not win the Irish Lottery. Is looking at sexually explicit material simply irresistible? Go to one of those video rental shops that has a back room instead of clicking links and images — a malware infection can cost you all your data and/or several hundred dollars in cleanup.. and/or many hours of your time..
Folks, the Internet is not Disneyland. Most knowledgeable people refer to it as the “wild, wild, West” (a reference to sheer lawlessness) but I like a different analogy better.. think of it as going into the Big City, and going down to the docks/warehouse district, alone, and at night.
You can do it, but you best be careful.

How To Block iFrames*
If you are interested in Tech, and visit Websites such as this one, it will not be very long before you read about Firefox. (In fact just this week I posted an article.) And, it won’t be long before you see NoScript mentioned. Odds are, you already have.
NoScript is a small program you download and add ‘into’ Firefox to enhance its functionality (these small programs are known variously as “add-ons”, “plug-ins”, and “extensions”– different words for the same concept.)
NoScript gets mentioned in the Tech media a lot because it is a security tool that automatically “blocks” (prevents from running) certain web page ‘elements’ (scripts) — Java, Flash, JavaScript, and XSS– from running unless you click the Option button and select “Allow”, or “Temporarily allow”.
Which puts you in control, and goes a long ways toward preventing “drive-by downloads“, and other malicious Internet attacks and activity from occurring should you happen to visit a Website which has been “poisoned” by a hacker.
(I don’t mean to depress you, but the current state of the Internet is so insecure that this can be, literally, any Website.)
By default, NoScript is a powerful tool (to read the NoScript “About” page, click here) and for many people is the primary reason they have made the switch to Firefox.
Tip of the day: Enhance your NoScript protection by turning on the IFRAME blocker feature.
IFRAMES are another dynamic Web element that cyber-criminals are now using as an “attack vector” (aka “method”) with great success. Like the scripts mentioned above, IFrame attacks can happen invisibly and automatically. Oh, the joys of Web 2.0!
[note: today’s advice should be of interest to Mac and Linux users too.]
1) In Firefox, click on “Tools”, then “Add-ons”
2) Scroll ’till you find NoScript, and click the “Options” button. (If you have not yet installed NoScript, click the “Get Add-ons” icon in the upper-left.)
3) Click on the Plugins tab. Place a check in the “Forbid <IFRAME>” checkbox.
That’s it. You’re done. Now when you visit a site that uses IFrames, you will have to approve them (aka “whitelist”) before they’ll appear.
[Note: the scripts and tools (Web 2.0 “features”) mentioned in this article are NOT in themselves bad or dangerous, and it is thanks to them that the Web is such a rich and interactive environment.. but, in the wrong hands they can — and are — being used with criminal intent.]
Related: A short video tutorial for using NoScript can be seen here.
Today’s free link: One of the more disturbing (outright alarming, if you ask me) hacker uses of IFrame attacks is the alteration of Search Engine results (Yes, you can’t truly trust Google, Yahoo!, or MSN anymore) and Internet Security blogger Bill Mullins has posted an excellent article on this subject, Fake/Redirected Search Results – Consequences for You

Protect Yourself With a Router
Increase the security of your Internet connection for less than $50.
For those of you using a DSL or cable connection to surf the Web, you should be aware that your connection is “always on”. That means your computer is able to go online and get security updates and other useful items without your being present, or even aware of the activity.
This is a mixed blessing, as it can also do other–less wonderful–things without your knowledge. You can increase your Web security by preventing being visible to miscreants out there on the Web by hiding your computer’s IP address (a set of unique numbers used to locate and identify machines on the Internet) behind a router which is capable of “NAT” (some manufactures call this “with firewall”) — as almost all current makes and models are — such as those sold by Linksys, Netgear, and D-Link. You can research models on the Web, and then find the best prices on such shopping sites as www.buy.com and Shopzilla.
I have seen Wireless-G routers for $20.
If your router allows for MAC address filtering, turn it on! Use a browser to log onto the router’s administrator’s control panel as per its instruction booklet (often it’s http://192.168.1.1) and click on “enable MAC filtering”. This will prevent other computers from getting a free ride by accessing your network and your Internet connection.
(If you have never logged onto your router and set a password, and your manual is lost forever, instructions can be found at the manufacturer’s website.)
Putting a router between your modem and computer will also allow you to share your Web connection with multiple computers. Most routers have Ethernet ports for four of your computers.
Note: If you purchase a router that includes a wireless access point, there are some measures you should take to secure the wireless transmitter/receiver as well. First, turn on and configure encryption of at least WPA as per the instruction booklet, and 2nd, disable the SSID broadcast. These two steps will prevent intruders from “seeing” your access point, and encryption will strongly discourage a snoop from capturing and reading your traffic.
To read my instruction article covering the security enabling steps (including illustrations), please click here. Doing so will put a shield between you (your computers) and the bad guys out there on the Internet, and increase your privacy and security.
* For those of you who don’t already have a router/WAP, or are just thinking about getting a newer, faster, one, you may also want to look at Wireless standards and you–buying a new WAP.

I am doing an on-site job today, and so I must re-post a prior article. This article describes how to get more out of IE 7. It appeared 1/2/08–
Once again, I am reminded that the simple things often make the best topics. I showed my screen to a client during a support session, and they asked me “how do you do that?”
I didn’t know what they meant, and was startled to learn that what they wanted to know was how did I have Internet Explorer “pre-set” to several of my mailboxes, and Google’s search page. To be more specific — they didn’t know about tabbed browsing, and weren’t real sure what Favorites were either.
Tip of the day: Stop repeating yourself, get the hang of IE 7’s features. New to IE (but not to Firefox, Opera, Netscape, and others) is a feature called “tabbed browsing” which allows you to open multiple websites within a single window, and quickly switch back-and-forth between them. In this screenshot you can see how my IE usually appears.
As you can see, I typically have five “tabs” open: my Google home page, an online dictionary, Tech–for Everyone, Hotmail (now “Windows Live Hotmail”), and my ISP’s home page. When I shut down at night, I click IE’s red “X” — the big red one in the upper-right corner –and am presented with the window (You may see “You are about to close multiple tabs. Do you..?” Click on the “Show Options” link.) shown below.
and I select (check) “Open these tabs the next time I use Internet Explorer”. This option allows me to skip having to open five tabs and navigating to each of my regular websites each morning.
To open a new tab, and this works in every browser I’m familiar with, hit ctrl+T. Depending on your Settings selection (under “Tabs” in Internet Options) this new tab will open to your current Home Page, or to a “blank page”, as shown below.
Now I can type “http://www.mychoiceofsite.com” (no quotes) into the browser bar, and there I am. Or I can click on the gold star for my list of Favorites, and launch (open) a site from there.
“Favorites” is Microsoft’s word for “bookmarks”, and in the world of PC’s the two words are interchangeable. If I stumble across a particularly interesting and/or useful Website that I know I will be returning to frequently, I can “bookmark it” by clicking on the green + on-top-of-the-gold-star icon and select “Add to Favorites” (or hit Ctrl+D). My mailboxes, my favorite tech websites, Google, and an online dictionary are in my Favorites list, so I can launch (open) them with a click — which saves on my typing.
To close a tab, simply click on its “x”; which is not red but grey. The tab must be “active” (selected) to be closed.
Now set your Tabs options to keep all your browsing in one instance of IE (instead of opening another IE, a new tab will open). In the upper right corner, click on the “Tools” menu and select “Internet Options”. Look down to the Tabs area and click on the Settings button.
Now select the radio buttons to change “in a new window” to “in a new tab”, as shown below.
Today’s free link: (You knew this was coming … right?) An application that has gained quite a name for itself is the “alternative” browser called Firefox. If you haven’t tried this powerful, free program, nor learned about its nifty “Add ons”, I suggest you give it a test drive now. Click here to download Firefox and then click the Tools menu and then Add ons. I suggest you start with NoScript and AdBlock Plus, and then explore the vast assortment.
Why? Because Firefox is not as (globally) popular as IE, it is less targeted by hackers. (When I recommend Firefox now, I am recommending Beta 3. I do not recommend using Firefox 2)
