wgr614 and d-link dap-1522

I have had a wgr614 v7 for quite sometime (connected by wire to a pc, another ethernet client). I also use my laptop and iphone as a wireless clients.

All has been well until I got a d-link dap-1522 to create a wireless bridge to connect a dish network set-top box and a lg blu-ray player. Setup was not too difficult and the connections worked fine. But I found that after sometime, the wireless network would not work!!!

For example, I get back home and my iphone that had got disconnected would not connect so is the case with the bridge and my laptop.

What I know is that as soon as I make any change to the setting on the wgr614, and it forces the router to re-start, everything works like a charm!! Same if I disconnect power and re-start. All this time, no issue (as you might guess) with the wired connection from this router.

Any help would be greatly appreciated.
