Anyone uses PlayBook with D-Link DIR 655 or any 802.11n draft Wireless Router? Are you facing wi-fi connectivity issue?
I am using D-Link DIR-655 with latest firmware.
My PalyBook would constantly disconnect between 10 sec and 2min after connecting, I would have to turn wi-fi off and back on to connect again. How to know it is disconnected? Simply in browser type any address, the blue status bar will move to 1/3rd of the way across the screen and then stop and not move... This is extremely fustrating.
I have iPhone4 and laptop that all connect fine with the same wireless router.
After couple of tests, these are things what I know:
PB wireless connection constantly dropped with N mode, this happens when
1. router set to: N only, WPA2 (or auto between WPA, WPA2), AES(or auto between ASE, TKIP)
2. router set to: N+G mixed, WPA2, AES(or auto between ASE, TKIP)
PB wireless connection very stable with G mode, this happens when
3. router set to: N+G mixed, WPA, AES (or TKIP or auto)
It looks like PB will choose N from the mix of N+G when WPA2+ASE is available. This is different from iPhone 4, for the same mix setting, iPhone 4 knows to choose G mode.
Settings 2 allows various wireless devices connect to same router in G or N mode, while setting 3 only allows G mode. because of PB, Now I have to set WPA and all of my wireless devices have no choice to use G mode...
I think PB has problem with draft version of 802.11n, while Apple is more smart here, it ignores draft N...
Should I go buy a new Router or wait for PB new update?

Here are my DIR-655 settings:
Version: 1.33NA, 2010/01/19
channel width 20/40
I also had a guest mode enabled (G). You can try connecting via guest to force G-connection. However, N works fine.
It will drop connection if I am too far. Otherwise the clearer the signal, the less likely it'll lose the connection.

My dir-655 firmware version 1.34NA, 2010/04/16
I tried your settings but didn't help.
No matter what WPA mode is selected, as long as Cipher is ASE, router status/wireless shows PB is on N, and PB constantly drop connection (signal is very good but no connection).
No matter what WPA mode is selected, as long as Cipher is TKIP, router status/wireless shows PB is on G, and PB does not have any connection issue.
I tried to remove the security mode, and forced to N mode, same connection drop problem.
So it is defiantly related to N. I dunno why your DIR655 has no such issue but it does happen to me...
And thanks your Guest suggestion, it is indeed a workaround, I created a guest zone with TKIP to force to G, only used by PB, works like a charm

I hate to have to be on only G as well but it seems to have fixed the stability issues, thank you! Can anyone answer aandras question about how to tell if you're on N or G on your PB, I thought it was as simple as looking under the wifi status but apparently not?

login to your router's admin page (normal http://192.168.0.1), under status / wireless you can find the list of devices that connectly connect to this router, as well as other info like, on G or N.
