Need Help With Network Instability

Iceman · 12-20-06, 01:04 AM

I have a website of my own and a forum on it where I have posted some of the typical things I find and the solutions...many are wireless related but you may want to read through some of them.

http://www.cyberallies.com//support/nfphpbb/index.php

some other sites of use to me over the years are....

http://practicallynetworked.com/

and

http://www.speedguide.net/

let me know what you find....

for it to lose connection so often through the router and not when it is directly connected is suspicious to me....unless your isp is no longer seeing the MAC address of your network card or something which can be "Spoofed" in your router settings...in ther words to make it work when it is directly connected to the computer then entering the mac address of your network card into the router so the modem thinks it is still connected to the internal ethernet card....this should or is not normally a problem with my company anyway but may be what is happenening in some way...just something to try fooling around with...instead of rebooting let it connected drectly to you computer via an ethernet cable.....get connectivity....then bring up a dos prompt and run

ipconfig /all

to get the mac address of your ethernet card...then hook it back up to the router without rebooting the modem and entering the mac address of the ethernet card into the router....it should still think it is connected to the modem directly.

We have an ADSL phone line. Wether your service is via cable or phone line, have you checked with your cable or phone service to make sure that the line quality is what it should be? We've had problems in the past cause by poor line quality. The phone company came in, found the cause of the problem and everything went back to normal. No changes to our own hardware/software whatsoever.

Well, that's a wired router, so that makes things a lot easier.

First off, look up the standard login information. Looks like "192.168.1.1" and something like "root:admin" or "admin:admin". Your instruction manual should have this stuff, or there should be a sticker on the thing.

Second, disconnect the internet cable.

Third, type in "192.168.1.1" in your browser and enter the login stuff. Visit all the configuration pages and write down all the entries. You could have PPoE information in there from your university, DNS entries.

Next, use the hard reset switch. You'll probably need a pencil. Sometimes routers will just get some funky "deny" policy setup for your system and they need a hard-reset to clear it out.

Then open up a web browser and type in "192.168.1.1". Use the login, password.

From there, it gets a bit hairy. The university probably has their own settings, and when you go somewhere else, you may have to revert back to an "default" config.

Actually, I'm no longer at my university - this is a home network.

Don't worry aboyut it though - I got tired of the constant problems I had with this Lynksis piece of junk and just bought a D-Link DI-604 instead.

It is working perfectly, unlike the Lynksis (which will make a good paperweight).

Thank you for your help everyone.
