fresh install WIFI extremely slow

Hardware Compatibility
1

Hello! Thanks for having me!
I am Linux illiterate.

(Please don’t assume I have 2 friggen clues what I or you are saying)

Installed MATE 16.04 and wifi is extremely slow.

The wifi adaptor is a Realtek, RT3090 Wireless 802.11n 1T/1R PCIe

Could someone please spoon feed me a solution?

I have tried this:

@BlackBox:~$ sudo modprobe -r rt2800pci [sudo] password for god: @BlackBox:~$ sudo modprobe -v rt2800pci nohwcrypt=1

insmod /lib/modules/4.4.0-31-generic/kernel/lib/crc-ccitt.ko insmod /lib/modules/4.4.0-31-generic/kernel/drivers/misc/eeprom/eeprom_93cx6.ko insmod /lib/modules/4.4.0-31-generic/kernel/net/wireless/cfg80211.ko insmod /lib/modules/4.4.0-31-generic/kernel/net/mac80211/mac80211.ko insmod /lib/modules/4.4.0-31-generic/kernel/drivers/net/wireless/rt2x00/rt2x00lib.ko insmod /lib/modules/4.4.0-31-generic/kernel/drivers/net/wireless/rt2x00/rt2x00mmio.ko insmod /lib/modules/4.4.0-31-generic/kernel/drivers/net/wireless/rt2x00/rt2x00pci.ko insmod /lib/modules/4.4.0-31-generic/kernel/drivers/net/wireless/rt2x00/rt2800lib.ko insmod /lib/modules/4.4.0-31-generic/kernel/drivers/net/wireless/rt2x00/rt2800mmio.ko insmod /lib/modules/4.4.0-31-generic/kernel/drivers/net/wireless/rt2x00/rt2800pci.ko nohwcrypt=1

The first command turned off the wifi, the second command reconnected it. There was no improvement in speed.

Then I tried this:

echo “options rt2800pci nohwcrypt=1” | sudo tee /etc/modprobe.d/rt2800pci.conf

Then did a reboot, no change in speed.

Then I went to “edit connections” in the network manager, seclect Ipv6 and selected “Ignore” That definitely caused an increase in download speed, from .4 up to 7.5. Still pretty slow, but not glacier slow.

Some previous people in another forum have asked for some outputs, so here they are:

thanks for telling me how to do that.

i was getting grief from other forum moderators. code tags have been added to OP

5

Have you tried changing wireless channel in the router to say 6 ?

6

i’m looking into how to do that now.

it was not first guess, as the problem seemed driver related as it only occurred immediately after a new OS installation.

7

Hi Mark Greaves

First of all, thanks for taking the time to help me. People like you are why I love Linux.

So, I changed to channel 6 and the speed bumped up from 7.4 Mbps (with Ipv6 set to IGNORE, I think that this change won’t survive a reboot, but i’m not sure (selecting ignore bumped my speed from .47 to 7.4)) to now over 20 Mbps.

Should I put the IPv6 back to auto?

Speedtest is showing downloads over 50 Mbps on the LAN desktop, just by comparison.

8

Well,

I rebooted, and went back to .46 dnld speed.
Changed IPv6 back to automatic, got 7Mbps…

Now i’m back to totally terrible download speeds.
Yeah, i don’t know what I did, but i’m getting 0.4 Mbps download again…

So, i’m in a hotel using their wifi, and the same problem. Non-existent wifi, it’s so slow.

Edit connections, “Ignore” iPv6, and boom, 10Mbps download.

Not super fast, but fast enough to write and post this message.

Any ideas, anyone?

Should I just reinstall a different flavour of linux? Could this be a driver issue?

10

You could try, but you’re gonna get the same driver :wink:

If you can give me a couple of days I’ll see what I can dig up, just stupid busy ATM … meanwhile have you got a USB wireless adapter you can use ?

11

No, Mark, it’s not a really essential laptop, I’m in Montreal for 2 weeks, until I get home, and this speed is actually suitable for the hotel WIFI, it will stream video, so it’s not that slow.

You think if I put linux Mint back on it I will have the same problem?

I just happen to like Ubuntu MATE, but it’s not critical that I keep it. I should probably put Lubuntu or something elso really lightweight…

12

If you’re using Ubuntu 16.04 it will have EXACTLY the same drivers as Mint 18 … so theoretically there should be no difference as far as wireless goes.

I say “theoretically” because I’ve seen differences before where there should be non … eg. Wireless not working in say Mint 18 but working perfectly in Peppermint on the same hardware … this shouldn’t happen because they both use the same kernel, and yet occasionally it does.

This is the world of computing … weird s**t happens sometimes :wink:

I should probably put Lubuntu or something elso really lightweight...

Maybe try Peppermint 7 :wink:

13

Ok,

I’ll give Peppermint a go.

I take it you are (one of) the developer(s)?

I’ll post back with the results of the install with respect to WIFI speeds. Just have to find a USB drive or blank DVD somewhere…

Thanks

14

Who me ? … good gracious no … well okay a little bit, you got me :slight_smile:

15

don’t know why i couldn’t log back into my last registered account… but anyway, Mr. Greaves, I’m writing from my laptop with Peppermint freshly installed.

It’s a slick OS, but i’m still having shit WIFI speeds…

the wired speeds a wicked fast, but the browser is still very slow despite wired download speeds of 164 mbps…

I’m currently doing the apt-get update… taking forever. had to plug into LAN as wifi was giving me .46 mbps from speedtest.net

I obviously need help. beginning to suspect hardware…

16

Ah, figured out how to login…

Hello Mark,

So, I managed to install the 32 bit version of Peppermint, I’m actually not sure how to determine if my processor is 64 bit capable or not, so i went with 32 by default.

Nice slick OS, I like it and will stick with it if I can figure out this wifi problem.

The wifi is still pitifully slow. .42 down, wheras 164 mbps down on the LAN cable.

However the laptop is still operating slowly as well, the browser seemed to take longer than it should to load pages, even on the WLAN.

I’m beginning to think there could be a hardware problem.

On the install I did not check “download updates while installing” but I did check the other box, the codecs or proprietary drivers one…

Thanks for your time.

17

well, I got fed up and tried to install the 64 bit version, and on the second or third screen it asks to connect to a wifi network (no wifi present when I run live USB) it doesn’t actually list my available wifi networks in the area, but instead asks me to chose the network called (my network adaptor) Ralink corp. RT3090 Wireless 802.11n 1T/1R PCIe

Weird.

18

You wanna try the really old rtl2860sta driver from here:
http://cxperimental.weebly.com/updated-rt2860pci-ralink-mediatek-wireless-driver-2015-for-linux-3x-40-kernels.html
?

If so, (with an ethernet connection) open a terminal and run these commands in sequence:

sudo apt-get install build-essential

then

cd ~/Desktop

then

wget http://cxperimental.weebly.com/uploads/4/1/8/2/4182100/rt2860git14-7-2015.tar.gz

then

tar xvf rt2860git14-7-2015.tar.gz

then

cd ~/Desktop/2010_07_16_RT2860_Linux_STA_v2.4.0.0

then

make

then

sudo make install

then

sudo rmmod rt2800pci

then

sudo modprobe -v rt2860sta

and if wireless works … let me know how the speed is.

Be aware this will NOT (at the moment) survive a reboot … after a reboot you’ll be back on the rt2800pci driver until you run:

sudo rmmod rt2800pci

then

sudo modprobe -v rt2860sta

again … but if this works, we can make this permanent.

19

The last command gave me this: (wifi not working)

sudo modprobe -v rtl2860sta
modprobe: FATAL: Module rtl2860sta not found in directory /lib/modules/4.4.0-51-generic

Thanks for trying, Mark.
