Hello, Apologies if I've missed a previous post on this. I did search and didnt' find anyting. If you know of something I've missed please feel free to redirect me to the proper thread. I have a WRT55AG that has DHCP enabled. I have 2 G clients, 1 A client and 1 direct connect to the 55. Everything has been working fine until this morning. With no changes to anything the DHCP on the G channel stopped working. The A channel continues to work perfectly (I can release/renew dhcp at will with no problems). The DHCP is set up to deliver IP's in the range 192.168.2.100-150. If I configure a static IP outside of the DHCP range (e.g. 192.168.2.151) and enter the DNS info manually everything works as expected. In essence, the router is working fine, only the DHCP is not vending to the network on the G side. I have powered off everything (up to and including the entire network at one point) disabled and re-eneabled DHCP and completely reviewed the configuration for the router and both computers, nothing has changed since yesterday except that the lease on one of the computers expired (set to expire daily as default) and it is unable to renew. Has anyone seen anything similar to this?
