About a week or two ago my connection speed to my router dropped from 100 Mbps to 10 Mbps (that's what it says in the icon in my system tray). I have another computer hooked up to the router and the connection is fine on that one. I can't recall anything I might have done that would have caused this, but my internet is running really slow now.

My router is a WRT54G, but I have the wireless features turned off. Everything hooking up to them is through ethernet cables. My network card is called "NVIDIA nForce Networking Controller" and is part of my motherboard (K8NE Deluxe). My ISP is Cox and I have Windows XP Pro

Things I've tried so far:
-Resetted modem and router
-Uninstall/Reinstall network card drivers
-Updated Motherboard drivers
-Ran Ad-Aware/Spy-bot/AVG/Mcafeeonline
-Changed ethernet cables

Any help would be greatly appreciated. Thanks alot.

Hello bobdole118 and welcome to G2G,

Please follow this link on both PC's and post your results for each.

Please also let me know what tier you are one?

Hey, thanks for the reply.

On both computers i get a download speed of about 8.5 Mbps, which is above Cox Preffered (7Mbps). On my computer I get an upload speed of .29kbps, which doesnt make any tier on the list. On the other computer the status bar never budges and eventually it just says "Your Upload speed is ???".

I'd also like to note that the performance of my internet seems to be fluctuating. During the day (like right now) it seems to be better, and I can make it around websites ok, but it's still way slower than it's supposed to be. At night, though, it slows down really bad and it takes me several minutes to load a page. Should I try to do this speed test when that happens as well?

[SpaceCowboy706]

No don't waste your time with another test.... I know the tier speeds also... read my profile

What is the manufacturer and model of your modem? and try this test out on both pc's:

1. Please Connect just one computer directly to your modem via a Cat5 Jumper
2. Unplug Power from the modem
3. Turn off the Computer
4. Plug Power into the modem
5. Wait for it to sync all the way up (Send and receive lights are solid)
6. Turn on the computer
7. After it boots click on "Start"
8. Click on "Run"
9. Type in: cmd and hit enter
10. From the command console type in: ipconfig and press enter
11. Copy down the default gateway address.
12. From the command console type in: ping defaultgateway -l 1000 -n 225 and then press enter. Where it says default gateway in the ping command just insert the gateway address you copied down in step 11.
13. After the test is complete, post your results back here

Remember do this for both PC's and post all the results, after done with the first PC... make sure to start again at step 1.

Hey,

My router is a Linksys WRT54G

When I hook up my computer directly to the modem and do everything you said, all it says is Media Disconnected when I do an ipconfig. I waited a while and it didn't change. I tried doing this before and had the same problem. It's actually what made me try changing the cables, which didn't fix anything.

On the other computer it says this:

Ethernet adapter Local Area Connection:

Connection-specific DNS Suffix . :
Autoconfiguration IP Address. . . : 169.254.17.155
Subnet Mask . . . . . . . . . . . : 255.255.0.0
Default Gateway . . . . . . . . . :

C:\Documents and Settings\Wesley Jung>

On both computers I couldn't access the internet.

My router is a Linksys WRT54G

I need your MODEM manufacturer and model, that is your router?

See this picture to see where your modem is at in your network:

[bobdole118]

Oh crap, sorry.

It says Toshiba Cable Modem PCX2200

[SpaceCowboy706]

When i had you follow the instructions is POST # 4 at step 5..... was the CABLE light blinking slow, fast, or solid.

and also was the PC light blinking slow, fast, or solid.

[bobdole118]

Both lights were solid. The only blinking one was Data, but that one is always blinking.

Lets try selective startup on just one pc, to make sure there are no software conflicts:

1. Click on "Start"
2. Click on "Run"
3. Type in: msconfig and click the OK button
4. Click on the "Services" tab
5. Put a check in the "Hide all Microsoft Services" box at the bottom
6. Copy down all remaining items that have a check in the box (to be readded later)
7. Uncheck any other items still left in the Service Box.
8. Click on the "Startup" tab
9. Copy down all items that have a check in the box (to be readded later)
10. Click the "Disable all" Button
11. Click the "Apply" and then the OK button
12. When it asks to "Restart" select "Yes"
13. After the Pc Restarts you will get a message telling you that you have entered Selective Startup....
.... just put a check in the box and click the OK button.

Check your speeds here and post your reults.

[bobdole118]

Download speed - 8.5 Mbps
Upload speed - 341 Kbps

This is on my computer, not the other one hooked up to the router.

Edit: Do you think there's any chance this problem is virus related rather than hardware related? I've ran a lot of tests on my computer, but not so much on the other one. Also, the other computer uses norton...which isn't that great.

follow post 10 for the other computer as well and lets compare the speeds

[bobdole118]

Ok this is weird. I'm getting different results from the speed test than I got the first time around. On both computers, booting with a selective startup or not, I'm getting about 8.5 Mbps Download and 500 Kbps upload.

Edit: Actually, my internet seems to be a lot faster lately and it's not slowing down to crawl at night anymore. I'm thinking that part was just my ISP being lame. My computer is still only "talking" to my router at 10 Mbps though, when it should be 100. I went into my NIC settings and set the speed to Force 100 Full Duplex, but it didn't change anything.

Call Cox and ask them what your "transmit" is? (AKA Upstream Power Level)

[bobdole118]

Hm...well it seems to have fixed itself. I reinstalled my NIC drivers again and this time it worked...for some reason...

Anyways, my connection is back to 100Mbps so woohoo!

Thanks alot for you help!
