Received OSMC wifi-ac adapter - ISSUES


#203

I get same result with 2.4ghz which is working


#204

So you can ping now, the only thing not working is DNS?


#205

No i cant ping using the 5GHZ


#206

What is ping 10.0.0.1 giving you?
Also what is route -n and arp -a saying.


#207


#208

That is really odd
You see the ARP of the gateway, you have RX and TX packets but Ping doesn’t work.
Can you ping another device in your LAN and check after that with arp -a if you see the MAC of that device
Is your IP configured by DHCP?
Is the 5Ghz network configured on the same LAN as the 2.4 GHz one?
What make/model is your router?


#209


No its not. Using static IP


#210

Can you for test purpose use DHCP?
This is really odd that it shows the ARP resolution.

Next option would be to check packages with tcpdump.


#211


My router is netgear x6


#212

As written,really strange. Suggest to check with tcpdump what packages go out and what might come in or not come in.

sudo apt-get install tcpdump
sudo tcpdump -n -i wlan0


#213


Using 2.4ghz mode


#214


Using 5ghz mode


#215



#216

Please install a package arping (you’ll need to be on 2.4 GHz or wired):

sudo apt-get install arping

Then on 5 GHz, for a few local IP addresses that you know currently exist, run:

sudo arping -v -i wlan0 -c 3 <IP Address>

#217


Test on 2.4ghz


#218


Journalctl

Test on 5ghz

Test ping on 5ghz


#219

The next step is to see if you can ping to the Pi (10.0.0.12) from:

  • the router (10.0.0.1);
  • another wired device on the network; and
  • another wireless device on the network.

#220

Ok, I will ask to google how to ping from my router.

thx


#221

Most router have a “diagnostic” menu entry that has a ping function.


#222

Diagnostic tab is missing on my firmware version (bad luck)… I will try to update it so
