mtmt88 - I've tried to explain that many of these cases we have at work are out of our control because MS decided to make our PEAP authentication more secure and not allow expired certs and/or certs that don't reference a CA installed on your phone. A couple things to try. Use a laptop/tablet and connect to your work wifi so you can read the cert. Check for the expiration and the see what the root CA is. If it is exprired, tell your IT to "do the needful". If cert is self-signed (i.e. you don't have the CA installed on your phone), export it from your notebook and email it to your phone so you can install it - reboot and try again.
How to read/get the certificate after connecting to that network via laptop?
I have the same error - Connection unsuccessful: Your phone couldn't reach the Wi-Fi network abcd. The difference is that this is my Home WiFi, not office. Another interesting fact is that all other devices can connect fine - Office Thinkpad W510, my Dell Inspiron, Wife's Lumia 520 and the Surface - only my Nokia Lumia 925 has this issue. Tried deleting and adding it again, didn't work.
Any help will be appreciated - downloading big apps or even streaming uses up my data and this is driving me crazy. Sombody please help.
Yeah windows phones are just rubbish. Crashes, glitches, errors, even all the apps suck.
FYI - many of these Wifi woes will go away with Windows Phone 8.1. I'm using the dev preview and found a few options I haven't seen before when adding a wifi network manually.
1) Connect using: user name+password, certificate, SIM
2) Server certificate validation: none, always ask me, certificate authority
3) EAP method: PEAP MS-CHAP v2, TTLS
Number 2 has been the source of many problem - self-signed certs meant you had to get them and add them to your phone as I've described previously. Now, we can do like iOS and Android. Say none. I used always ask me and was presented the cert info to which I said ok. This worked.
Number 3 means there is EAP-TTLS support now. I know a few of you were waiting for this.
I believe this puts WP on par with the competition...once 8.1 is generally available.

Have you tried turning off the SmartScreen Filter in IE's advanced settings?
Also, are you talking about 8.1 or 8.1 GDR1?
