I've been using the BUFFALO WHR-HP-GN router for a few months now with no problems and 2 days ago my internet has been going at dial up speeds one second, then fairly fast another second. I connected directly to the modem to see if that was the problem and I get 16 mbps download speeds but wirelessly its about 1 mbps. I live in apartment and have a good wireless signal. I tried resetting the router, going back to factory settings, changing the channel but to no avail. I am using DD WRT v24SP2. No changes were made from the time the router was working well to the time it stopped working. Any help would be appreciated.
Firmware: DD-WRT v24SP2-MULTI
