Router/Internet Temporary Loss

crystalv · 04-21-2008, 07:03 AM

Well, here is another one I am having trouble figuring out...

Have a 2003 server that is a domain controller, DNS, and DHCP server. We have a wireless based internet with a static IP that comes into a wireless router that is used to share internet wirelessly, but has the routing functions turned off. This goes to a gigabit switch, which is attached to the server.

The server has a static IP with the following:
192.168.1.100
255.255.255.000
192.168.1.1

192.168.1.1

The DHCP server has 192.168.1.1 set to be the gateway and 192.168.1.100 set to be the DNS.

Everything was working fine for about two months.

Now we are getting really odd errors that I can't trace. We started losing internet for about 5-10min or so, and then would get it back for a little bit, then lose it again. We tried resetting everything. This would seem to fix it for about 5-10 min, but then it would go bad again. Then replaced the wireless router, however this did nothing.

I then noticed that when we were losing internet we were also unable to ping the router. We replaced the cable, changed the port on the gigabit switch. We are able to ping the server and all other network computers when we can't ping the router.

Ended up replacing the router and changing its IP address to 192.168.1.99 and changing all the server information to match. This worked for about 48 hrs. However, we are beginning to have the problem intermittently again. This time it is only happening every 15 min or so and only lasts about 30 seconds. We are unable to ping the .99 router, which has our internet coming into it. I did keep the .1 router plugged in just for testing purposes, and when we lose internet now, we are still able to ping the .1 router.

Does anyone have any ideas?
