Wifi Internet Issues ( Cisco E3000 )
Hi Experts,
I am having a issue with both of my Cisco E3000 Wireless Routers that we are using at wireless Relay points. Ive noticed in the past week that certain computers can connect to the to the access points and are handed out the correct DHCP address but can not access the internet. (Neither browsers or pinging out, but anything on a 0 subnet it can ping just fine)
I have a feeling this has something to do with the Dual Band... The wifi points give off g and n signal ( 1 at 2.4 and 1 at 5ghz)
Certain computers can not pick up the 5ghz signal but can connect to the 2.4 signal... but all computers can see the 2.4 ghz signal. I figure this is because of the wifi cards in each of the laptops but I find it strange that some computers can connect to the 2.4 signal and receive no internet access but are fine connecting to the 5ghz signal with wifi and Certain computers can connect to the 5ghz signal with no wifi but are great on 2.4
I know that sounds confusing , but any tips would be great... I have tried firmware updates and rebooting the wifi points... I have not tried a full reboot of our Zyxel Zywall USG 100 router because that would bring everything down for at least 10 minutes and I can not afford to do that at the moment.
Thanks!

Could you paint us a little better picture of how the E3000 routers are connected to the ZyWall, where DHCP comes from, and anything else you can tell us about the setup (without revealing passwords or usernames)?

Hi!
We have two buildings, each e3000 in both buildins. DHCP is setup in the Zywall and the E3000 are connected to the netgear switches. DHCP is turned off in the E3000's and they are connected in the LAN and not the WAN.
I found it strange that this suddenly started happening, I was able to reboot the Zywall last night and the wireless interent is working now... we will see if it fixees the problem
As for the setup , Were using a WPA-2 encryption... were not using any sort of MAC filtering
Its also on the same subnet
Let me know if I am missing something... took a screen shot of my wireless settings

Since the problem seemed to clear up when you rebooted it, in the ZyWall check the DHCP lease length, and see if you can mine how many unique devices regularly connect from the logs so that number can be compared to the size of the DHCP scope.
