lmao. I'm also having the same problem and it's over a year since someone posted in here.

I can' believe this has not been addressed with firmware or something. haha So I just recently bought the dir-825 and the dap-1522 and same problem. I don't mind the router but I'm not sure yet about the bridge. I've set it up now that it would be impossible to for it to drop a connection but it still does.
I set the channel to 11 and if it drops again I'm going to the store for a refund. I haven't even had it 10 days so I'm scrutinizing this very closely. Good lord, shame on you dlink! Maybe it's time to go back to Linksys or try another brand.
Hell, I might just bring all the hardware back for a refund or exchange for a different brand altogether. Going to do more research this time though.
OMG - it just did it again while I was typing this. lmao, back to the store with all products. I'm effin fed up with this shat.
I dropped over $200 for both these devices and and a dlink wireless adapter never agian! lol
PS: I feel bad for you folks that weren't able to bring your hardware back but I feel lucky to have gotten this frustrated and found this post in the short time that I've owned this hardware so that I can return it ALL to the store. Linksys here I come!
