Some SSID not found #64
Comments
Hello Martin, I had the same issue as you reported: my laptop (running Ubuntu 19.04) wireless card (rtl8821ce) apparently worked with the current version of this driver (latest commit, August 16), i.e. it detected most of the SSIDs of my neighborhood. Unfortunately (and quite strangely) it could not detect the wifi signal from my Freebox, which could be detected by my smartphone, another laptop, etc. The solution for me was to use an older version, I chose commit 6fcab13 of March 1 (Fix compilation against Linux 5.0.0) since my Kernel version is 5.0.0. Now it works like a charm! I hope this helps you while waiting for a fix. |
hello, |
I bisected the problem. Note that it also doesn't work with the current latest commit, 55b90f4 . I hope that this information helps someone with better technical habilities. I'm available to run all tests you want if it can help. Meanwhile, I'm happy with that older version that works for me. Thanks for the fish, |
Sam problème some ssid not fond |
Same ISP, same issue. Had to use 6fcab13 as well to work around it. 6274276 for some reason (probably a mistake of my own) refused to compile. Am using Mini 4K router, don't know if the problem appears with all of Free's hardware but they must be doing something different with their WiFi signal. Tried multiple options in router wifi config none of which made the SSID visible by the recent commits. |
FWIW: same ISP, same issue here too. I've checked out 6274276 and installed it. I'm now seeing Freebox ESSIDs, and I'm connected to mine.
@mquinson: Thanks for bisecting a working commit And thanks Tomás for your work on this driver. I may provide some help testing, but only for a short period, as I don't own that laptop. |
Same ISP here, same device (Freebox), but no SSID shown with #6fcab13
Thanks to work on this ! |
I also have a Freebox. I tried to compile the module from the latest commit on Kubuntu 19.10 (kernel : 5.3.0.18.21). I wasn't not seeing my home wifi. So as a workaround, I'm booting Kubuntu with an older kernel and an older module compiled. |
@mquinson Which kernel are you using ? |
|
Hi, |
Hi, using a manjaro linux, kernel 5.3.11-1, i tried the 16 last commits with no success for 2.4Ghz (1ddc1d9 to 697c5ab) ended with using AUR version on 5Ghz SSID which is ok at home, but only at home : i will have problems in some places where i won't be able to connect... |
I have the same problem, with that same ISP |
As explained in my previous post, I managed to use my laptop's RTL8821CE wireless card and to see my Freebox SSID after installing version 6fcab13 of this driver on a laptop running Ubuntu 19.04 (kernel 5.0.0). Today, after upgrading Ubuntu to version 19.10 (kernel 5.3.0-24-generic), the wireless card was not working anymore... Looking (again) for a solution to this problem, I've found a package in the universe repository of Ubuntu 19.10 containing a driver for the RTL8821CE wireless card. After removing the old driver ( |
Oh interesting, so Realtek's drivers have indeed been implemented in Ubuntu 19.10. I've been holding off on upgrading because of reported issues with Kernel ver 5.3.xxx. Will try it out next weekend and report. EDIT 14/12: Running Ubuntu 19.10 now, and can confirm this driver is now unnecessary. Driver in Ubuntu repos is perfectly functional albeit not installed automatically. |
I can also confirm that the wifi works for the Kernel 5.3.0-24-generic (and 5.3.0-26-generic) with the package |
Thank you so much for this thread, I also confirm that Before I could detect some networks, but not the one from Freebox. Everything is fine now |
Note: For people now running the Apparently I advise not to upgrade, however if this is too late for you (or for new installs) reverting package to previous version solves it. You might wanna hold the version from future updates as well after that. |
That will be an issue for the next upgrade to Ubuntu Focal. The package is based on the version |
I've started a new thread about this bug on launchpad: |
Thanks. Everyone in this thread should mark themselves as affected in Funeoz's launchpad thread to give the bug visibility and hopefully get some able stranger to fix it before 20.04. |
hi everyone, |
If this works, maybe you could ask for a PR on this repo. |
Thanks aauzi for your workaround I did succeed to get my Freebox SSID with it. Otherwise I could not get it on a laptop running Ubuntu 19.10 |
The update of the driver to the version 'Realtek v5.5.2' introduce a check of the DR broadcasted in the WLAN_EID_SUPP_RATES IE. As a conseconsed AP with 22MB or 33MB Data Rate are filtered out. The check has been added in to function collect_bss_info of rtw_mlne_ext.c and performed in the function rtw_validate_value of rtw_wlan_util.c Adding these constants will allow to make the AP available again. Even if I did not observe any issue, I don't known if the driver is able to support such data rate. Anyway this patch permits to connect again on "Freebox" AP, the modem provided by French ISP "Free". Issue tomaspinho#64
Fix now merged into master. Closing this issue. Thanks everyone! |
Just to say that the fix has been merged for the packaged version |
The fix has been released for the Ubuntu package |
I still have the problem on an HP256 G8 on a Linux Mint Uma kernel 5.4.0-74. I tried the Ubuntu package and compiling from this source in master and all branches discussed here. So I think it is really an issue. should I open another issue? |
Hello,
first of all, thanks for this driver, it's really helpful as I have a network card that is not supported without it.
My problem is that while it seems to work correctly, the laptop fails to detect the set-top-box of my internet provider (
ESSID:"Freebox-58EB78"
). That's weird because the laptop detects other SSID that seem very similar, but not the one I'm interested into. Other laptops connect to this SSID with no problem.I'm not sure about the information I should provide to help debugging the issue. Here is the output of
iwlist wlo1 scan
on another laptop, that do see the SSID:Here is the full output of the same command on the machine using the rlt8821ce network card:
I'm really puzzled because the rtl card sees the same Cell 01 than the working one, but not the Cell 02. I fail to see any change between the machines that may explain this.
I understand that you don't have a RTL8821CE card anymore and that you cannot really help me here, but I'd be really grateful for any help you could provide.
Thanks,
