Very unstable WiFi

Maybe driver for radio1 is busted.

I thought so before. Seems it is the faulty ath9k driver.
Can’t wait for the fix… Will it ever be?

Pinging my Samsung Note 4 or other smartphone on Wlan1 give me this (device located by the router):

Additionally, each 5-30 mins. my smartphones get reconnected (short disconnects, no matter which free channel and/or crypt method I choose). This is happening from the first TO run. None of the updates and rescue flashing solved this! My TP-Link TL-WR1043NDv2 (LuCI OpenWRT), placed before in the same corner of my desk, did not give me any issues for 2 years of online work!
I’m really, really disappointed.

This is a firmware issue with the 5 GHz card occurred since update 3.3. I am also having that problem.

Thanks, but I was talking about 2,4 GHz (wlan1) :slight_smile:

Oke, enough with the jokes.

Could you give me the following output.

iw wlan1 scan

Do hide your own SSID(wifiname) and BSSID (macaddress)

Put the output in preformatted text < / > in the editor menu of your message.

Well. I’m not alone here. I saw some posts on this forum, telling the same. Also, a friend of mine, owning TO, has the same issue.

So looking at the output, it looks like your neighbors are kind of far away from you right? Because you have almost no other WiFi-networks surrounding you.

Did i conclude this right?

Yes, you’re right here.

Could you set in the

/etc/config/wireless

option channel 'auto'
option txpower '19'

to

option channel '6'
option txpower '16'

If you still have the problems with it, try the following

iw reg set CZ

also change in the wireless config the country settings to CZ. Then look if things have changed.

Does this problem occur 24/7 so to say or only a few moments of the day?

Have you also looked at the hardware side? Tighten the antenna screws and also the u.fl connector.

Are the antennas also the antennas that you got with the Omnia or are they different antennas?

I have the same issue and with yesterday’s update disconnects start to be even more frequent. It’s the worst wifi router I ever had.

@yorik

I replaced right from day one, when I got the Turris Omnia, the two pre-installed wifi modules with MikroTik’s R11e-5HacT and R11e-2HPnD cards. With these cards, I get fantastic performance, 100% stability (not once a disconnect) and the signal-strengths to avoid any additional repeater in my large house. I used quite a few different routers in the past and for me, TO ist the best and not the worst I ever had :slight_smile:

It’s not the worst router because the rest of it is simply fantastic!
I hope they will soon fix the wifi problems.

You got two monsters in your Omnia that have gone savage, by having the tx-power boosted up to 30 dBm (2.4 GHz monster), the other one i forgot how much it’s savage power goes. What do you expect …:joy:

With different wifi cards it’s completely different device;) My main complains are about wifi reliability, so your comment isn’t that relevant.

The only good part about omnia is throughput: I can use about my full 1Gbit, but it’s very hard to find a server which allows to use it for something except of tests. But there are a lot of bugs in software (ipv6 dhcpd doesn’t work, not clear how to properly allow external traffic to internal servers, etc) and wifi is just terrible. And even SFP doesn’t work. Right now I’m reflashing my old Netgear R7000 to put it back as primary router and wait until omnia will be fixed or I’ll buy something better.

Thanks for your help, but weakening of the signal should not be a solution to this problem, am I right?

I did this before the first run.[quote=“Big_boss, post:52, topic:1698”]

[/quote]

They are the preinstalled (stock) ones.

There is no case of “weakening”, because the 2.4 GHz only puts out a max of 16 dBm already for each chain. So putting it on 19 does not suddenly change to 19.

That is why i said put it on 16 and the channel use a fixed channel to test it.
