I have a BMC42142 wireless adaptor
lspci -vnn | grep 14e4: 02:00.0 Network controller : Broadcom Corporation BCM43142 802.11b/g/n [14e4:4365] (rev 01)
and I can't connect to the wireless lan. I'm using

My wireless modem is TP-Link TD864W and I share this information 'cause I cannot say for sure whether the problem is caused by my adapter or by the modem. Here are the symptoms:
- I cannot connect to my wireless modem from my laptop. It stays in the "connecting" status.
- But my android tablet can connect to it.
- I can connect to my neighbor's modem and even a wireless printer two floors down.
What I've tried:
- I tried to connect by disabling DHCP and choosing a static IP. This time it says "connected" but I could not browse any sites.
