Was having problems with the WAN dropping repeatedly. Upgraded firmware to newest 126.96.36.199. So far the internet has not dropped. I enabled https for remote management and could no longer get to router. Disabled and can get to router.
I do not have Qos enabled, or any ACL policies. I only enabled IPS for all IM and P2P. Clients were having problems getting to webmail.aol.com. Browser would just hang. Remembered sometime ago that I had an issue with webmail after blocking an IM port. Cisco had me disable half of services, then half again to narrow down service. ICQ instant messenger was the culprit. Disabled blocking for ICQ and now able to access webmail.
Still however have problem with https remote management.
