We have a master controller that has two interfaces enabled one goes to the LAN and one is connected to a DMZ for Guest access and RAPs this has worked great for the past couple of years but in the past couple of weeks we've started getting issues with RAPs tasking 20 minutes to connect to the controller and clients unable to connect to the SSIDs broadcast by the RAPs, this is intermittant.
Also our Guest access intermittantly slows to a crawl and can take the best part of 5 minutes to open a web page on a client or timesout altogether.
There's no errors as far as we can see in the logs but going through various different troubleshooting steps we noticed the routing table on the controller has two default gateways and lots of statics and would like to know if this could be causing the issues we're seeing, the 172 networks are on the DMZ and the 10 and 192 are on the LAN.
Codes: C - connected, O - OSPF, R - RIP, S - static
M - mgmt, U - route usable, * - candidate default, V - RAPNG VPN/Branch
