Hi i just reinstalled to Ubuntu 14.04 LTS and im having problem with wifi.It keeps disconnecting it really annoying.How i can fix it?

Dear Borkoborko,
can you send the ouput of ipconfig and iwconfig?
Yours faithfully,
M.

For ipconfig it says command not found and for
iwconfig:
eth0 no wireless extensions.

wlan0 IEEE 802.11bgn ESSID:"******"
Mode:Managed Frequency:2.437 GHz Access Point: **:**:**:**:**:**
Bit Rate=150 Mb/s Tx-Power=14 dBm

Power Managementff
Link Quality=68/70 Signal level=-42 dBm
Rx invalid nwid:0 Rx invalid crypt:0 Rx invalid frag:0
Tx excessive retries:0 Invalid misc:97211 Missed beacon:0

lo no wireless extensions.

That's because there is no command called ipconfig in GNU/Linux. Try
Or even better, in order to solve this, we need to know what kind of WiFi card is installed, please post the output of the command:
Best regards,
HMW
