Can connect using my EVO4G (CM7.2) and my TF101 (Revolver 3.7), using the "WiFi Advanced Configuration Editor" tool on the market.
For the above devices, the WiFi SSID shows as "Work" (Secured with WEP), with WiFiAdvanced on the device, i would:
1) In Settings/Wireless & Networks: select the network: "Work" (Secured with WEP)
2) enter some garbage text as the key, click connect
3) turn off/on the WiFi
4) open WiFiAdvanced and select the "Work" connection and change the settings (as listed below)
5) then within 5-20 seconds the device would connect (and stay connected) to the network without issue
This procedure is SOP for every non-ICS Android device at the company and works flawlessly.
Additionally, I've used other procedures for attempting to configure the network using the "Add network" button in the Wi-Fi settings area with the same SSID name "Work"; however these settings do not appear to stay in place, as the wireless network "Work" still shows as "Secured with WEP" and will not connect using the 802.1x EAP settings.
However after asking around the office (I work in the Infrastructure team with the Network Admins - one of which has a HTC One X that appears to be having similar connectivity issues to this specific network) turns out that most other ICS devices, and specifically for my new Nexus 7 (Stock 4.1.1, not rooted), the "Work" (Secured with WEP) network is never replaced with the 802.1x EAP version; And after adding the new network or setting up via WiFiAdvanced there is a duplicate "Work" network that shows as "out of range".
On the duplicate network listing, when clicking on the "out of range" "Work" network, it shows Security 802.1x EAP in the details (but no option to Connect). I have more than 2 bars on over 6 WAP's in the distributed wireless network (Cisco wireless devices configured to use rotating keys and assign via DHCP) and have full signal on all my devices.
My Nexus 7 does work very well at my home, running WPA2 (TKIP + AES) at 150MBPS (138mbps reported), and at the coffee shop next to work; leading me to believe it is not a functionality issue with the wireless adapter.
WiFiAdvanced settings for the "Work" network:
BSSID: [no change]
Hidden SSID: [unchecked]
Key Management: [None, IEEE8021X]
Auth Protocols: [Open, Shared]
Group Ciphers: [WEP40, WEP104, TKIP, CCMP]
Pairwise Cipher: [None, TKIP, CCMP]
Security Protocols: [WPA, RSN]
Identity: [my domain/username]
Password: [my domain password]
Client Certificate: [empty]
CA Certificate: [empty]
Private Key: [empty]
Yes, i know there are other threads out there, I've spent the majority of my day researching and testing - to no avail.
Can anyone suggest steps that may assist in getting the Nexus7 able to connect to this network?
Asof Oct 15, 2012: This issue has been fixed in the 4.1.2 OTA.
