Wifi - wrong speed reported

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi all,

Using Fedora 25 on my laptop I found out it supports 5ghz. Great, some
more speed, since the 2.4ghz band is a bit crowded in my
neighboorhood....

However, both NetworkManager an iwconfig report only a poor 6m...:

wconfig  wlp3s0
wlp3s0    IEEE 802.11  ESSID:"<very secret>"  
          Mode:Managed  Frequency:5.26 GHz  Access Point:
<xx:xx:xx:xx:xx:xx>   
          Bit Rate=6 Mb/s   Tx-Power=20 dBm   
          Retry short limit:7   RTS thr:off   Fragment thr:off
          Power Management:on
          Link Quality=65/70  Signal level=-45 dBm  
          Rx invalid nwid:0  Rx invalid crypt:0  Rx invalid frag:0
          Tx excessive retries:0  Invalid misc:0   Missed beacon:0

Can't be that bad.... Luckily, my (Fritz) access point reports a
healthy 650 Mb. Also, downloading a large file goes easily 2x faster
from what you would expect from reported transfer rate.

I noticed this behaviour before, reporting only 1 MB on an older
laptop. 

What's happening here? I look a bit like large number (>100 Mb) is cut
of to only the first digit. Anyone seen this before? How to handle?
