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.

Lost the Setup CD? How To Connect a Router*

Reader asks how to connect to the Internet without the original CD

Q: “How can I connect to the Internet with my laptop via D-link router from desktop? We have no CD ROM for d link.”

A: You do not need the setup CD to make a router work (frankly, the following is my preferred method, as the CD’s usually install unnecessary “bonus features”.) Here is how you establish Internet connections (aka “configure a”) on a router.

1) Assign your PC an IP address in the same range as the router’s default address– for most routers, assign the IP 192.168.1.2, but since this is a D-Link router, use 192.168.0.2.
(Look to “Assign Address” here for Illustrated instructions.)

2) Connect the PC directly to the router with an Ethernet cable.

3) open a web browser (IE, Firefox, Safari) and enter the IP address number of the router into the address bar. (If you don’t know this, look to the router manufacturer’s Website for “default settings”). Typically, this is 192.168.1.1, or 192.168.0.254 — but D-Link uses 192.168.0.1.

4) Enter the default Name and Password (again, look to to the website’s support page/FAQ’s if you don’t know these). But typically these are “admin”+”admin”, or “admin”+”password”.
D-Link’s default is admin/admin.

Your are now in your router’s “web interface” Control Panel, and you can enter the PPPoE setting provided by your ISP. Typically all you need is an identifier.. which is an e-mail address + password.
If you can’t find or remember these, contact your ISP’s support. D-Link’s Wizard will help.

[note: Once your ISP has connected, and while you’re in the Control Panel, set your router’s security configuration, and set a new password (and write them down). Illustrated instructions can be found here, https://techpaul.wordpress.com/2008/01/01/how-to-secure-your-wireless-network/]

5) Return to Network Connections (from Step 1) and reset your PC to “Get address automatically–DHCP”. Reboot your PC if necessary.

Wolfenstein Enemy Territory is a stand-alone multiplayer game in which players wage war as Axis or Allies in team-based combat. In Wolfenstein Enemy Territory Axis and Allied teams do battle in traditional single scenarios, or wage war through a series of linked scenarios in a totally new campaign mode. During combat players gain experience and skill, and through battlefield promotions are awarded additional abilities that remain persistent across an entire campaign.
