I'm having problem getting a reliable connection on the hotel WiFi. nmcli device wifi list shows three networks with the same SSID on the same channel:

>nmcli device wifi list
SSID           MODE   CHAN  RATE       SIGNAL  BARS  SECURITY

Same Net SSID  Infra  6     54 Mbit/s  40      ▂▄__  WPA2                                                                                          
Same Net SSID  Infra  6     54 Mbit/s  30      ▂___  WPA2  

I should normally be able to connect on the first but:

  1. the connection is difficult to obtain and
  2. once setup, bandwidth is abysmal, so I suspect I'm connecting to the wrong one.

How can I check to which hotspot I'm connected, and how can I force the connection to the good one?

Running Kubuntu 16.04, nmcli v1.2.6

Machine is a Lenovo P50 with Intel® Dual Band Wireless AC 8260 2x2.

About a year ago, I had a similar problem on a customer's premises, and fixed it by forcing the machine to avoid 802.11n (modprobe iwlwifi 11n_disable=1) but this didn't work this time.

    The 3 hotel hostspots use the same SSID, and all on channel 6. – xenoid May 7 at 6:56

    If the hotel has a, bad WiFi setup, maybe it would make more sense addressing the problem with them – Rui F Ribeiro May 7 at 7:32

    Well, works well with my wife's iPad, so it may not be the hotel. – xenoid May 7 at 7:36

    Apples and oranges. I do advise adding technical data to the question and basic data about the equipment, it would be better than the last comment. But nevertheless this is a group about Unix and not debugging hotel WiFi problems – Rui F Ribeiro May 7 at 9:00

    (thecnical correct answer : the ipad has a decent WiFi chipset and by default uses 5GHz, the WiFi interface in the question is in a crowded 2.4GHz band) – Rui F Ribeiro May 7 at 9:10
