Hi Team,

The HP ProBook 470 G1 is currently on a pretty good special, but 2 of the first three that we have deployed seem to have wireless issues. Note that this is not an HP beat-up - just an advisory that we suspect there may be a bad batch of cards, so keep your eyes open.

Unit Specifications:
P/N: F3K32PA
Wireless Card: Mediatek MT7630E 802.11bgn Wi-Fi Adapter (as reported by Device Manager)
OS: Windows 7 x64 (factory installation)
Driver Versions Tested: 5.0.37 and 5.0.38

Symptoms are that the wireless will go for a while and then disconnect. Windows will show you the list of available networks, and it seems to after a minute or two it will reconnect, and then disconnect again after a minute or two. Intitial Googling shows we are not alone with this issue. A suggestion as to force the encryption to TKIP instead of AES, but for us this did not resolve the issue (tried on one machine with one AP).

Initially HP sent us unpublished driver version 5.0.38 to try (the installer gave us an error, so I did a right-click driver update within Device Manager instead), and initially the issue went away, but after the next reboot the wireless was once again misbehaving. Note that over the two machines, 3 different APs of different brands have shown the same symptoms.

HP have ordered a replacement wireless card (intending to use a different chipset I believe) and expect to send someone out to install it tomorrow. If I remember I'll post the results. Feel free to give me a nudge if I forget.

Cheers
Mike
