After unplugging from ultra dock, wifi will be connected...

Does this dock support wifi?

Dear jcong,

The same topic was already discussed at this forum thread.

Actually, the issue was solved by BIOS Update Utility v1.12 or later.

Thanks for your reply

while my bios version is 1.10

BIOS: N1WET31W (1.10 )

this is my office laptop, software and hardware are maintenanced by IT dept., I can't upgrade biso, so is there anyother solution?

Dear jcong,

the actual solution is implemented by Embeded Controller(EC) program v1.15.

You can confirm the EC program version at BIOS Setup or MSINFO32.EXE. In case the EC version is not v1.15, I'd like discuss with your IT dept. to apply the EC program.
