Network card bitrate blocked at 87mbps
Network card bitrate blocked at 87mbps
Hello everyone, I have a question to ask anyone who wants to help me. It affects the bitrate of the wifi card on my Lenovo laptop (Buster) that mounts an Atheros PCi card and a Realtek USB dongle (TP-LINK). The problem is that with both of them, the maximum connection of the card is 87 mbps. Is it a drivers problem? I tried reinstalling them and upgrading the kernel from 4.19 to 5.5 from backport but I got nothing.
I prefer to use a usb dongle because has a greater range (5ghz ac). The others devices in the network like smartphones or Windows PC run up to 250/300 mbps without problems.

Re: Network card bitrate blocked at 87mbps
Have you actually checked the speed of the connection?
On my system:
As you can see, the iwlist(8) output does not show the speed of the connection.

Re: Network card bitrate blocked at 87mbps
My ISP brings me 1Gbit in theory. In practice, never less than 130/150 Mbit (FTTH)Head_on_a_Stick wrote:Have you actually checked the speed of the connection?
Actually the speedtest reports 65/70 Mbps from my laptop, my phone instead 150 Mbps, both with same protocol 802.11ac under 5Ghz frequency.
I think the limit marked in iwlist is the maximum speed dictated by the driver, as if it didn't recognize the AC protocol.

Re: Network card bitrate blocked at 87mbps
Hi anapol,
It seems like there is no firmware blob needed for that driver. From what I gather around the net, the drivers for that chipset are still evolving. Have a look at:
https://github.com/aircrack-ng/rtl8812au.git
You could try the latest driver from that git rep and comile for your kernel. There are hints that SecureBoot needs to be disabled, check the readme.
If you are unsuccesfull with that, if it were me, I would for the moment accept the limitation of the current driver and/or look for another dongle with better driver support in Linux. Atheros chipsets are generally better supported.
regards, santosha

Re: Network card bitrate blocked at 87mbps
Hello santosha, thanks for reply.
I will try that drivers.
I just want clarify that also with the integrated PCI Atheros I have a bandwidth limit (30 Mbps exactly half of USB dongle). The difference is the frequency (2.4Ghz),
Do you think it can be a limit of a driver's mainboard?

Powersave settings may also lock the speed at a lower bitrate.

I have no particular settings related to powersave. I don't think that's it.

Re: Network card bitrate blocked at 87mbps
Are you sure it's not the router? I get 300 mbps service to my house. With a direct ethernet cable connection to the router I get 300+. With my wifi I get ~100. The router wifi transmitter is the limiting factor, not my wifi card.
Re: Network card bitrate blocked at 87mbps
Yes, I'm sure. With others devices connected to same SSID there is no problem.sgage wrote:Are you sure it's not the router? I get 300 mbps service to my house.

The problem is related only to the Wifi cards on my notebook (With debian distro). Both the integrated Atheros(30/35Mbps 2.4Ghz) and USB Realtek dongle (60/70mbps in 5Ghz). So annoying.
Re: Network card bitrate blocked at 87mbps
If there's one thing I've learned from nearly 4 decades in the biz, it's that computers can be extremely annoying! I wish my router could pump out more than 100 mbps. OTOH, got enough EMR flying around here as it isanapol wrote:Yes, I'm sure. With others devices connected to same SSID there is no problem.sgage wrote:Are you sure it's not the router?

Re: Network card bitrate blocked at 87mbps
Suppose you would do some test like with a bootable USB stick:
Take e.g. Debian Live, Bunsenlabs Live (pretty fast, Debian based) and some other Distro like OpenSuse based.
Look if they recognize your WiFi card else take another distro so you can compared the "Live-USB" speeds.
Check the driver from them and then the fast ones are very interesting to see how you may get to those drivers....
Or you find out they use the same driver... but looking in their setup you maybe can find the differences so you know what might help.... and try that, if it makes sense based on working hypothesis that there's logic behind the differences...

iwlwifi will run much quicker than that but sometimes requires a little driver tweaking for optimal performance. Pretty good thread here -

I think iwlwifi is only related to wireless intel adapter. Anyway I upgraded it to latest package avaliable and nothing changes.
I still have to try the advice of andre@home, I will try different bootable distro.
Re: Network card bitrate blocked at 87mbps
Nothing changes. I focused on the internal Atheros PCI card which also works badly with Ubuntu, Bunsen and other Rhel based distro. I think that with the drivers installed it cannot recognize 802.11n protocol (in fact I don't see any 5Ghz SSID networks), besides other limits probably.andre@home wrote:Suppose you would do some test like with a bootable USB stick:

My PCI Wireless card is : Qualcomm Atheros QCA9565 / AR9565 Wireless network adapter with last ath9k drivers installed and It supports IEEE 802.11b, IEEE 802.11g, IEEE 802.11n protocols.
No hope I think.

Re: Network card bitrate blocked at 87mbps
OK, a pity... but at ;east you know your limits now for sure.
Is this result in line what the chips can do according their specs?
And no 5GHz?

The network card shoud work at 5Ghz according to specs, but is not so.andre@home wrote:OK, a pity... but at ;east you know your limits now for sure.

I have no other idea. Maybe I should consider buying a usb dongle different from Realtek and Atheros? Ralink Maybe?
