Aha thanks, sorted now after rebooting. Initially I didn't want to reboot as I thought the exchange limited me at 26 dB for disconnecting lots of times this morning, thinking rebooting would make it worse. I've seen happen in the past when I got pushed up to 9 dB and then 12dB when I fiddled with router config/reboots or wiring, took 3 weeks to recover it back to 6dB or so.
IP profile is still 512kb, gotta wait it out I guess.
