Hi everyone, I configured the wtfast settings and was already logged in without issues. The router logged me out after adding some changes (dont recall which exact changes they were) and it now complains with error"internal error. Session cache inconsistency" when trying to login to the wtfast...

This happens at least once a day, for 5-10 min at a time. Everything works fine otherwise, save for maybe slow download speeds occasionally. Any ideas? I know i should attach a log here, but I'm not sure which would be helpful, so I will add one once I know which one to include. Thanks
