Losing internet connection on wireless router

[Ltat42]

Hi All,
I have a Linksys wireless router in an office connected to a cable modem.
There are four computers (sometimes 5) in the office that use the router.
Of the 4, 3 connect using a wireless adapter card. The 4th has an adapter card but will not get a good connection to the router or out to the internet.

We connected this computer to the router directly with a cat 5 cable, and disabled the wireless connection. It works good, but after about 10-15 minutes, the internet connection is lost. In order to restore it, I have to re-boot.
This goes on every day...

any suggestions?

Even with the computer directly wired with cat5 to the router it still drops internet connection? What OS is this computer running Windows XP ? If so is there a firewall running that could be causing issues? Is it up to date on its service packs?

Yes, it still drops. The puter in question is running Windows XP. I don't believe the firewall is the problem, it's disabled. I'm not sure about the service pack updates. They claim it connects to the internet, after about 15 minutes, they
lose their internet connection. They re-boot, everything works fine, about 15 minutes later - no internet.

ok well one thing they/you may want to check is in the routers config. Use a web browser to access the config and look for "MTU" enable and set it to 1500. Then see if that helps things.

Ok, I'll try that, and double check the firewall stuff. I'll re-post my findings.
Thanx...

Well, I went by the office, the computer in question would not connect through the router at all. I could not even access the router configuration - at all.

The computer is a Compaq, Windows XP, on-board NIC, and a linksys wireless pci adapter.

I removed the pci card - no change, still would not connect or access the router configuration. I hooked up my laptop with a wireless adapter, it would not connect at the location where the Compaq was. I removed that, connected the cat5 cable - boom! I got online - no problems, started surfing, worked real well. I unplugged that, plugged it back into the Compaq - nothing, would not connect to the internet, at all.

At a loss.....any suggestions?

You need to run a cat5 cable from the Compaq to the router. Once in there check to see if MTU is set right then check to see if "wireless" is enable. You may have to reset the router to its factory defaults but try the above steps first. If you do end up resetting the router to factory defaults make sure and upgrade to the latest firmware before you leave.

reinstall both newtork adapters?

Wait you had another computer connect with the cat5 that the compaq wouldn't connect with? Did you check the nic to make sure it was enabled? I know it sounds basic but sometimes the simple things are the overlooked problems.

I'm having the same problem as Ltat42. I'm using a Linksys WRT54Gv3 with freshly downloaded Firmware. My connection drops to all three computers at once. (1 HP Laptop w/XP, 1 AMD-64 custom w/XP and 1 Mac w/ OS10.3.9) I'm sitting here watching the power bars on my mac go in and out repeatedly. Linksys tech support is useless. So far I've spoken to 2 ladies from India. (I think)

I have SSID on. I've tried different channels. I've reset it to factory settings. I've tried WEP, WPA-SPK, No security...

What can I do? I'm considering getting a NetGear router... Are they any better?

Thanks,
Tim

How are all the computers connected to the router? If one is wired to the router does it also drop connection or is it only the wireless computers?

[timbiden]

Usually they aren't wired to te router but with the problems that I've been having, I hooked my PC up to it. And when my mac lost connection, so did my PC.

I was sure that it was just a wireless issue, but I think I'm wrong. The entire router seems to drop connection at the same time.

Thanks,
Tim

Depending on what sort of connection you use ie cable or dsl you may want to change the MTU settings in the routers setup. For cable you can go with 1500 for dsl I'd use like 1400. Also make sure the rest of the router settings are as they should be for your connection type. You may also want to make sure the router has the newest firmware installed. One last thing that may help is a bit of advice from Archangel that he gave a user in another post.....

"AP settings: make sure you do not have any differing RTS or segment setting in any of the network configurations including the AP. If the AP is set to auto discover along with the network cards, as soon as one with differing settins connects to the network, all will be lost (sounds dramatic, but its true). A safe way to do this, is to look at the routers wireless page, write down the values, and make sure in the hardware properties that they match on each of the wireless cards changing only the values that differ from the router."

As a last straw you can call the isp and have then check the connection point to your house. I have seen and heard that if water gets into the housing of those connections it can cause the connection to drop at times and be unstable.
