I installed Linux Mint for my father. Now he is complaining about very slow internet (wireless). Being far away from him, I asked him to give me the result of a few lines of code. Maybe you can figure it out what is going on:
The result of iwconfig:

Code: Select all

wlan0     IEEE 802.11bgn  ESSID:"default"  
          Mode:Managed  Frequency:2.462 GHz  Access Point: 00:50:18:3E:E0:30   
          Bit Rate=54 Mb/s   Tx-Power=15 dBm   
          Retry  long limit:7   RTS thr:off   Fragment thr:off
          Power Management:off
          Link Quality=57/70  Signal level=-53 dBm  
          Rx invalid nwid:0  Rx invalid crypt:0  Rx invalid frag:0
          Tx excessive retries:4  Invalid misc:112   Missed beacon:0

lo        no wireless extensions.

eth0      no wireless extensions.

and the result of lspci|grep Ethernet

Code: Select all

 02:00.0 Ethernet controller: Broadcom Corporation NetLink BCM57785 Gigabit Ethernet PCIe (rev 10)]

Any help is appreciated.

Which wireless card ?

iwconfig wlan0

https://en.wikipedia.org/wiki/Wireless_tools_for_Linux

Code: Select all

iwconfig manipulate the basic wireless parameters 
iwlist allow to initiate scanning and list frequencies, bit-rates, encryption keys... 
iwspy allow to get per node link quality 
iwpriv allow to manipulate the Wireless Extensions specific to a driver (private) 
ifrename allow to name interfaces based on various static criteria

If it is a broadcom wireless, check the forums or the Internet for issues with that particular device.

The only item I can see is power management being ON

--to get most performance, it should probably just be OFF (powered all the time), and keep alive

It is like you said, DrHu, it is the powermanagement. When my dad goes into batterymode, he cannot get an internetconnection.

Thank you for your answer, DrHu.
