I have some strange wifi problems with my asus eee pc (1215p) on ubuntu 12.4LST 32bit:

  1. I can't access the netbook (A) from another machine (B) within the same local wifi network. When pinging from B to A I get: Destination Host Unreachable.
  2. When I ping from A to B the reverse connection from B to A then works, but very slowly (500ms in average for a ping)
  3. When I ping then from A to B the average delay is normal (5ms average)
  4. In general the connection from B to A is very slow (data, ssh, ...)

    • lan works fine
    • ufw is disabled
    • issues occur in every wifi network

lspci says I got a 02:00.0 Network controller: Broadcom Corporation BCM4313 802.11b/g/n Wireless LAN Controller (rev 01), however http://www.ubuntu.com/certification/hardware/201202-10625/ states, that the wifi controller is a Atheros Communications Inc. AR9285 Wireless Network Adapter (PCI-Express), so I'm a bit confused on what is built in and which driver I should use. The installed driver is the Broadcom STA wireless driver.

Anyone with similar issues?
