Can you post a show interface vlan 1? Is the VLAN 1 interface up? I dont see any access interface assigned to VLAN 1 to bring the interface up.

If they are both the same size internet connection regardless of ISP. I would run a routing protocol like BGP with the service provider this will provide and active/active redundant network. If they are diffrent size internet circuit sizes then this would be and active/standby setup. How to...

What kind of WAN circuits are these internet connections? I see above you mentioned static routes above is there any routing protocols running? example....BGP?

Any luck?

Thinking about this more try setting both T1s to line independent clocking.

Try these two lines of config. no network-clock-participate wic 0 no network-clock-participate wic 1 This will put each T1 in there own clocking domain. Then set all the T1s to line for timing. I think this was the fix. Will check my old TAC case when get back to work next week. Let me...

I have never messed with Extreme but on HP switches its called tagged and untagged...meaning .1q packets...maybe thats an option on extreme.

Are there any errors on the uplink ports? Is Spanning Tree running across links or do you have layer 3 switches in the accesss closets?

How is the clocking setup on the T1 controllers? What kind of CSUs are you using?

I would explore the possiblity of using EIGRP to load balance if that is possible with your network setup. EIGRP load balances by default over equal cost links.

What type of routing protocol are you using? EIGRP?

Where did you get this router from? My next thing to try would be to plug it into another cisco ethernet device and see what CDP tells you. Perhaps someone has changed the speed of the console port to perform an IOS upgrade and forgot to change it back. My next fear that is once you are able to...

What kind of cable are using between your PC and the router? Ensure that its a Console Cable AKA Rollover cable.

Anything that uses NetFlow

Remove those access list not sure what you are trying to accomplish with them. Test Setup a constant ping from one of the PCs that do not work to the firewall. While the ping is running do a show access-list on the switch to see if you are incramenting hits on one of them.
