An nothing at home changed? New device added, more devices connecting? Have you looked for a router firmware update? It's very strange that it worked and now it doesn't with no change to anything.
I, and others it seems, had similar WiFi issues after updating to OS 2.0.1.358.
I don't know if anyone ever found a permanent solution, but my only choice was to switch to my other Wifi access point. To this day, one works and the other does not and it all started with 2.0.1.358 upgrade.
I've had on and off wifi problems since I got the PB. Running a common Netgear G router. Usually it works, but there are days I can't get it to go online and I get that same couldn't resolve the host name error. I even bought a 2.4GHz spectrum analyzer to see what else was operating on the frequencies/channels and it did nothing to help me. There can be absolutely nothing operating on or near the wireless router channel I select, and still it just refuses to go online and I get the same error message. So it's not due to outside RF interference (such as baby monitors, phones, wireless cameras, alarm systems, other routers, etc..that routinely operate in the 2.4 GHz spectrum).
I just usually give up and try again later if it won't connect. But if I really needed my PB to go line for an important reason I guess I would just be SOL. It's almost so regular now I just learned to accept that it won't always go online when I want it to lol.
Edit: I just wanted to add that I've tried every piece of advice from others here on these forums to no avail - (e.g. reset or reinstall etc... does nothing).

This is a OS 2.0.1.358 issue as I downgraded and was fine until I went back to .358. Hopefully an update will fix this soon as my pb has been spending a lot of time on the charging doc lately.
I'm having the same problem, I keep getting "unknown network error". I to have tried everything. PB works great when linked to my BB 9930. This has to be something with PB OS.
Well, I figured out my problem. The receiver for my wireless turtle beach wireless headset (Xbox 360) was causing major interference. The headset hasn't been used in awhile so I kinda forgot about it. I unplugged the receiver and everything has been perfect for days.
Are you guys sure there isn't anything in your homes that might interfering with your WiFi?
I'm still havin this issue. I think it's a bug.
9/10 when I turn on my playbook to use, it gets the same messages. It shows connected with 98% signal to both my Access points.
My network configuration is correct. the IP is resolving. I can even ping SOME of my local network resources, like my NAS or my linux server.
I cannot RDP to my desktop, nor anything with any of the more complex protocols.
internet does not work.
The onyl way I manage to get back online properly is to reboot the playbook and my router and access points. Delete my network profiles and re-add. Then reboot again.
I'm doing a security wipe now to see if it resolves this. If it doesn't, I may have to consider leaving playbook. I cannot spend 15 minutes a day just to get online from the tablet.
