WiFi Module 3 is very unstable

Post by systemservice »

Hello,

I had asked here here which WiFi dongle is more stable and codewalker recommended WiFi #3 or #5A because they should be more stable than ralink(#0,#4).
So I have ordered some #3 and #5A and tested them, #5A looks good so far, but #3 is very unstable in Android PIE (20190726) (didn't test with other OS) and I don't know why.
I have tried with 2 different Access Points and different settings (20/40Mhz, choosed free WiFi channel) but no success so far.

Please see the screenshots:

Any ideas?

Thank you.

Some people reported the 2.4Ghz WiFi RF band has uncertain interference problems with USB 3.0 host ports.
They could solve the issue by using the OTG cable something like this.

Hi Odroid,

do you suggest to use the "micro USB 2.0 OTG (I port?)" ?

thanks
Manuel

Right. There is an OTG(micro-USB) port near the earphone jack on the N2 board.

Please note, that in my case the connection is interrupted approx. every 2 hours, you can see it in the monitoring logs on my first screenshot, it's not a connection speed issue.
Connecting "WiFi Module 3" to USB2.0 (OTG) didn't solve this issue.
Because it happens approx. every 2 hours, I thought that it may be a DHCP issue. But than yesterday I replaced "WiFi Module 3" by "WiFi Module 5A" and today I see no connection interrupts is the monitoring logs.
The access point and it's settings are same as before (still using 2,4 GHz).
So whatever it is, it happens only with "WiFi Module 3".

Nobody else is experiencing the same issue, maybe you just don't know about it?

With another Access Point "AVM FRITZ!Box 7490" - it's a high quality 170€ router used very much in Germany, the connection interrupts much more frequently, usually within 5-10 minutes, it's not usable at all.

We will check anything wrong with "WLAN powersaving" option in the driver.

Can you capture the "dmesg" and "logcat" outputs when you meet the disconnection problem?

Never mind. We will fix the issue soon.
We've spent a lot of time to implement the static IP feature for the Ethernet. viewtopic.php?f=178&t=35794

Try this. If it helps, we will add it in the next release.

Code: Select all

$ unzip rtl8192cu.ko.zip
$ adb remount
$ adb push rtl8192cu.ko /vendor/lib/modules/

Thank you, I have replaced the file now and will see what happens.

I wanted to capture the logs but couldn't figure out how to enable USB debugging while the network connection is interrupting, I tried connecting from PC to USB-OTG and USB 3.0 ports, but nothing happens also if I turn off/on "USB debugging" in Developer Options, adb doesn't find it, do I have to do more for this to work?

Unfortunately replacing rtl8192cu.ko didn't help. I would capture "dmesg" and "logcat" as odroid asked, but I think I need USB debugging because the WiFi connection interrupts frequently. It is possible to enable ADB debugging thru USB, which USB port shall I connect to?

You have to use the OTG port on the N2 board for the ADB connection as other Android smartphone does.

I don't know why, but I still cannot connect thru ADB. I tried different USB ports of my Windows 10 PC (USB 2.0, USB 3.0) and Micro-USB 2.0 OTG port of ODROID-N2. In Android, Developer Options and USB Debugging are ON, I also did OFF/ON. But neither in Android nor on the Windows PC something happens - no popups in Android, no popups and no new devices in Windows Device Manager, no devices in "adb devices". What else shall I try or does it work with a Linux PC only?

Can you try another USB cable to connect with PC? Or you can try to connect with another N2, OTG to HOST and run lsusb on another N2. Another option is to run logcat command and save the output after opening Terminal App on N2 itself.

OK, thank you, I've been using something like https://www.hardkernel.com/shop/usb2-0-otg-cable/ plus USB male<->male cable and it didn't work, but than tried a cable like from Samsung Galaxy and than ADB has connected.

I have captured the logs. Here you see the monitoring log when connecting to the red access point (fritz.box, CH1) on the channel graph picture of my first post.
As you see, it looks terrible.
log.jpg
log.jpg (66.91 KiB) Viewed 18810 times
This AP is configured as:
[x] use 2,4-GHz
[x] use 5Ghz
[x] select channel automatically (but it remains on channel 1)
[x] use WPA+WPA2

This is FRITZ!Box 7490, an expensice and high quality WLAN router widely used in Germany.
There are no issues when connecting to this AP with Samsung Galaxy S6 or other clients.

dmesg, kmsg and logcat logs are attached below.

With the purple access point (IA1, CH12) on the channel graph picture of my first post, the connection was better, but it disconnected about every 2 hours and it took several minutes to reconnect, here is the monitoring log of using this AP:

I have also found out that WiFi Module #5A also doesn't connect to the red AP "fritz.box" properly, but other devices like Samsung Galaxy S6 do. Static IP doesn't help.
However WiFi Module #5A works well with the purple AP "IA1" (CH12), whereas WiFi Module #3 reconnectls about every 2 hours and it takes several minutes.

dmesg of WiFi Module #5A:

Sometimes I tried to reconnect by clicking WiFi OFF/ON, so if you see in the logs the driver was deinitialized, then probably because of that.

Re: WiFi Module 3 is very unstable

Post by codewalker »

I built other driver for 8192cu.
The Wifi #3 will use 8192cu.ko instead of rtlwifi.ko, rtl_usb.ko, rtl8192c-common.ko, rtl8192cu.ko.

Try this.

Re: WiFi Module 3 is very unstable

Post by systemservice »

Thank you codewalker. I continue testing but what I see so far looks good with the purple AP "IA1" - no connections interrupts for 3,25 hours (usually it had been interrupted every < 2 hours before).

EDIT:
After 24h of testing there was no connection interrupts with the purple AP "IA1". Now testing with the red AP "fritz.box" and it looks also good so far.

However I noticed that if you want to disconnect and reconnect / switch to another AP, then usually you need to turn OFF/ON WiFi to reconnect, but it also had been so before your update.

Re: WiFi Module 3 is very unstable

Post by Lodroid »

I recently got an odroid n2 with the same module 3. It seems that I'm experiencing the same trouble. I'm running "18.04.2 LTS (Bionic Beaver)" "Linux odroid 4.9.162-22" (the image that came with the odroid)




I noticed the wifi was quite unstable so I tested bandwidth with iperf. Here's a sample of module3 traffic through odroidn2:
[ ID] Interval Transfer Bandwidth
[ 4] 0.00-1.00 sec 317 KBytes 2.59 Mbits/sec
[ 4] 1.00-2.00 sec 208 KBytes 1.70 Mbits/sec
[ 4] 2.00-3.00 sec 0.00 Bytes 0.00 bits/sec
[ 4] 3.00-4.00 sec 62.2 KBytes 509 Kbits/sec
[ 4] 4.00-5.00 sec 1.41 KBytes 11.6 Kbits/sec
[ 4] 5.00-6.00 sec 0.00 Bytes 0.00 bits/sec
[ 4] 6.00-7.00 sec 0.00 Bytes 0.00 bits/sec
[ 4] 7.00-8.00 sec 288 KBytes 2.36 Mbits/sec
[ 4] 8.00-9.00 sec 0.00 Bytes 0.00 bits/sec
[ 4] 9.00-10.00 sec 0.00 Bytes 0.00 bits/sec


This bursty traffic is quite unexpected, but reproducible. I tested some other combinations (details attached separately).

iperf_laptop_internal.txt
Just for comparison, laptop's internal WIFI.
[ 4] 0.00-10.02 sec 28.2 MBytes 23.7 Mbits/sec receiver



My tests show the module3 adapter seems to work well with windows drivers.
My relatively old tplink adapter works on the odroid, although the form factor takes up two usb ports.
I additionally tested the module3 adapter on an x86 debian machine, but it never connected and crashed the kernel.

I got the module3 adapter specifically because I've found this kind of antenna achieves the best range, not to mention the possibility for an external antenna, which is beneficial for my application, however I do not know how to resolve these connectivity issues. Can anyone recommend an adapter known to specifically work well with the odroid n2? The OP said #5A worked, anyone else have experience to share?

I see you posted a different build in an earlier response, is it still recommended to try that? If that works will it eventually get pushed into an official build?

Thanks in advance

The stock driver in the Kernel source tree seems to be a root cause.
Once we switch it to Realtek's recent driver, the throughput is much better.
We will release a Kernel update package a few days later after some other tests.

Kernel 4.9.190 update on Ubuntu has the Realtek's driver for better WiFi Module 3 connection speed.
Please try it and let us know the result.

Try viewtopic.php?f=179&t=33865&p=263298#p263050 if you don't use Ubuntu. I've been using it a couple months, it's a big improvement. It's a dkms Realtek driver: apt install 8192cu-dkms Probably the same one as in the Ubuntu update.

I updated to the latest version I found at https://wiki.odroid.com/getting_started ... tion_guide
Ubuntu 18.04.3 LTS
Linux odroid 4.9.187-53 #1 SMP PREEMPT Fri Aug 9 06:12:18 -03 2019 aarch64 aarch64 aarch64 GNU/Linux
Same issue there, but I must be missing something.

Where is this "Kernel 4.9.190" you are referring to?

I also tried ab1jx's suggestion to "apt install 8192cu-dkms", but that gives me "E: Unable to locate package 8192cu-dkms", I'm guessing it's for some other distro.

Have you done

Code: Select all

sudo apt-get update
sudo apt-get dist-upgrade

Nope, I didn't realize it would be newer than the kernel directly from hardkernel.
That did it though: Linux odroid 4.9.190-62


There are no more dropouts either. I'd say the issue is solved!

I don't know why the bandwidth drops after it starts, it happens every time. Maybe it's instrumentation error or some form of buffer bloat.

The same thing actually happens with a wireless panda adapter I got in the meantime...
