I would first check that you are allowed to connect your non work device to the network, I'm assuming its not a guest network as its wpa, and maybe certain protocols are blocked?
Either way if you are not IT staff I would check your policies, we do not allow non company devices onto our internal network and come down pretty hard on rule breakers at my work.
I log in with my Windows XP user and password. Just need to use chat and email at N900
Yes, as do I at the office but, I can tell you for a fact that if your company abide to SOX or ITIL standards you will be breaching policies, check with your IT dept. We don't want you getting in trouble.
After reading some topics, at the end my N900 can connect to WIFI at work, but only internet, not email accounts, not IM accounts (skype, gtalk).
We have a WPA with EAP (PEAP, MSCHAPv2) WLAN. Must add proxy to surf the internet.
Is there sth I can do, or that is, only internet and no IM or email?
Thanks
I assume by "internet" you mean "world wide web". It sounds like they block outgoing access, and web works because it goes over the proxy. I would guess you are out of luck here, unless you set up some http tunnel... but that's almost certainly against your company policies.
Better solution is probably to use GPRS... of course your mobile operator could block things as well (on T-Mobile USA i can't use Skype or Google Voice, for example)
