Hi, To resurrect an old thread, we've run into an incompatibility that affects all Realtek chipsets (other than the 8188CE with latest drivers dated March 2013) which do not associate if we have 802.11b data rates present (mandatory or supported) but not ALL of them.
So, 1/2/5.5/11 enabled = works 11Mbit mandatory, all other 802.11b rates disabled (12Mbit/sec+ set to supported) = fail. The 8188CE driver update released this March resolves the issue with the 8188CE but other Realtek chipset users are out of luck. We're looking at disabling 802.11b entirely as this also resolves the issue. The workaround on the device configuration with this RF profile present is to set the Realtek NIC to do 802.11b only. For some reason, this works! Has anybody else run into this issue?
