Unstable wifi with Intel Wirelss 7265 on ubuntu 20.04

drapel sn

My Asus Zenbook UX304UA seems to have problems connecting to newer wifi standards. This first popped up when I was temporarily using my neigbhor's wifi and is now again constantly unstable when I am logged in to a semi-public company wifi. What is puzzling me is that my phone has no problems whatsoever. Additionally, the problem gets worse when battery drops under 25%...

I have ubuntu 20.04 running and already updated to the latest BIOS version of the notebook (UX305UA.302). The output of sudo lshw -C network is:

  *-network                 
       description: wireless connection
       product: Wireless 7265

       resources: irq:128 memory:dfa00000-dfa01fff

And ls /lib/firmware/ | grep iwlwifi-7265 yields:

I am connected in 2.4GHz. I came accross this post but that didn't helped much.

întâmpinați probleme de conectare la standarde wifi mai noi. Ce inseamna asta?

Uită-te la bușteni! `sudo journalctl -b 0 -u NetworkManager`. Citiți `man journalctl`.

Bună @David, deoarece problema a apărut doar anul acesta cu routerele mai noi, am ajuns la concluzia că ar putea avea legătură cu standardele wifi mai noi

Nu au existat suporturi wifi noi de câțiva ani.

da, răul meu. M-am gândit că cu viitoarea wifi 6 acesta ar fi putut fi un motiv pentru comportamentul instabil.... Am adăugat rezultatul jurnalelor legate de managerul rețelei de la pornire până la punctul în care a pierdut prima conexiune, @waltinator

@David 802.11ac a fost lansat în 2016; 802.11ax, alias Wi-Fi6, a fost aprobat pe 9 februarie 2021. Sunt de acord că *au* apărut îmbunătățiri recente.

Editați întrebarea pentru a afișa rezultatul comenzii terminalului: `nmcli device wifi list` Vă rugăm să redactați adresele MAC astfel: xxx GBR5 Infra 149 405 Mbit/s 74 âââ_ WPA2 De asemenea, este performanța s-a îmbunătățit dacă te conectezi la banda de 5 GHz?

@chili555, vă rugăm să furnizați referință, cei pe care i-am citit spun că a fost aprobat cu peste 3 ani în urmă. Un punct mut doar pentru interesul meu.

Vedem că sunteți conectat la punctul de acces bgu_extern și că există trei cazuri în intervalul de scanare. Vă sugerez să încercați să legați cel mai puternic dintre cele trei astfel: Ubuntu connect drops. A lucrat o vreme, apoi a început să scadă din nou

merci, buna idee. Legarea plăcii de rețea la un punct de acces o îmbunătățește, dar nu rezolvă problema în totalitate =(

întrebarea această in alte limbi:

Postează un răspuns

Majoritatea oamenilor nu înțeleg că a pune multe întrebări deblochează învățarea și îmbunătățește legătura interpersonală. În studiile lui Alison, de exemplu, deși oamenii își puteau aminti cu exactitate câte întrebări au fost puse în conversațiile lor, ei nu au intuit legătura dintre întrebări și apreciere. În patru studii, în care participanții au fost implicați în conversații ei înșiși sau au citit transcrieri ale conversațiilor altora, oamenii au avut tendința să nu realizeze că întrebarea ar influența – sau ar fi influențat – nivelul de prietenie dintre conversatori.
