HI,
Have VIM2 pro 1.4 and wireless is not working

how I enable it?

#4

VIM2 can have different WIFI chips
Check announce topic for validated chips
Sorry but pro version have not supported chip for mainline kernel
But we try change it in next releases

Hi @tsangyoujun,

I have managed to install openwrt (latest 0.6 version) on my vim2 max and was testing Ethernet connection speed.

To my surprise the speed is quite low. I get only 2-3 Mbit for download and around 1.5 Mbit for upload.
Vim2 is connected directly to my router and uses DHCP to get IP (it is on the same subnet as my PC).

My PC with Linux mint 19.3 connected to the same router gets around 110 Mbit in download and 13 Mbit in upload speed.

What am I missing? What are your results in speed test?

Best regards,
S.

#6

I can get warranty for openwrt its real 100 Mbit ethernet for both directions for ViM2
And 1000mbit for VIM3 and VIM3L
I have tested it already

If u have another result plz provide mode detail about your testing process

Hi @hyphop,

I was wrong, built 0.5 version and installed it to emmc and speed over Ethernet is excellent.

I do have some strange errors in kermit console while booting. Take a look here : Strange errors

My speedtest is this:

Retrieving speedtest.net server list…
Selecting best server based on ping…
Hosted by Terrakom [net + tel + tv] (Zagreb) [5.57 km]: 16.015 ms
Testing download speed…
Download: 137.54 Mbit/s
Testing upload speed…
Upload: 14.44 Mbit/s

So it seems version 0.5 works :wink:

Also on build 0.6 there is no wifi as you wrote on github page (wireless config is empty).

Best regards,
S.

  1. speedtest via web service like speedtest.net its only for internet speed connection - but not for ethernet or wifi :wink:

Also on build 0.6 there is no wifi as you wrote on github page (wireless config is empty).

i think u check this image ?
VIMx.OpenWrt.19.07.0.servers.test.emmc.kresq

! show me wifi_sdio and iwconfig output

Hi @hyphop,

I hope you are chilling and enjoying your vacation :wink:

Will try to flash 19.07.0.servers version. Btw I have build myself openwrt and flashed :slight_smile:

I don’t see any explanation what is the difference between server version and standard version of openwrt? Can you explain what is the difference?

Btw what is the signal strength on openwrt in your testing? I have connected to OpenWrt SSID and my observation is that wifi signal is quite bad but it shouldn’t be because of vim2 hardware spec ?!?!
Will report my findings tonight when I get back home.

One more question, have you heard of this ROOter firmware by http://www.ofmodemsandmen.com/?
They made ROOter firmware especially for work with 3G/LTE modems and it would be nice to have something like that for vims :wink:

Best regards,
S.

COOL :wink: i hope its was very easy :wink:

I don’t see any explanation what is the difference between server version and standard version of openwrt? Can you explain what is the difference?

server variant have some addition packages ( u can get more infoabout them from sources - https://github.com/hyphop/khadas-openwrt/blob/master/scripts/post_install_servers )

They made ROOter firmware especially for work with 3G/LTE modems and it would be nice to have something like that for vims

never hear about this FIRMWARE;)

i dont have any problem with modems in openwrt
i u still have problem plz inform me about them !

#11

Yes, I could say for dummies :slight_smile: And lighting fast too.

@hyphop,

I noticed that turning off wifi with wifi.off and then turning it on with wifi.on commands does nothing.
After turning wifi off I can’t turn it on, even after restarting networking with /etc/init.d/network restart?!

Only reboot helps to get back wifi on, very strange.

this wifi chips drivers from broadcom very limited have many problems!!! and need special modification for openwrt

step by step i will make it !!!

U and everybody can help :wink: ( check sources | fork | and improve )

PS: we have cool hardware and have nice openwrt software base - lets improve it together

PSS: i will post more info about WIFI and howto configure WIFI hacks and fixs - next time

Hi @hyphop,

openwrt for vim2 is definitively a promising firmware but for now is in fat alpha :smiley: unstable and not for daily usage.

Hopefully in time, we will have a mighty firmware.

Enjoy on your vacation, won’t bother you :wink:

S.

#16

yes - agree !!! but all problem is only onboard wifi (i know about this problems ) - i have test day by day : vim2 and vim1 like wifi + vpn router + ethernet extension - in 24x7 mode about 2 month already and i can say ) its usable already !!! ( but need some experience level)

openwrt can provide wide ranges of task - not only as wifi router!!!
every time - my choose is openwrt - like good base for many different projects -
i think its one of the best linux distros

PS: if u need stable openwrt + Aarch64 base - u dont have big choose :wink:
