WiFi connection Unstable

I just got this new Router. Freshly installed and upgrade to the latest firmware (Firmwareversion V1.0.3.80_1.0.1). I've manually chosen a wireless channel that wouldn't interfere with the one if my neighbours. Problem is I keep losing connection on wireless. Rapidly disconnecting-reconnecting. Happens on all wifi devices.

 

This is the only hint I get from the log:

It's impossible to have a stable line. What can I do? Wired connection are stable.

Re: WiFi connection Unstable

Long shot but is your dhcp lease time 60 secs?

Re: WiFi connection Unstable

Pressed the wrong button. 

also see two ips there are the MACs the same across all those logs ?

Re: WiFi connection Unstable

Couldn't find the DHCP lease time. Also those MAC Addresses are different.

 

Wireless Setup:

  • AX Enabled
  • Smart Connect Enabled
  • 20/40 MHz Coexistence Disabled (Default)

2.4GHz:

  • Channel set manually
  • Mode: Up to 600 Mbps (Max)
  • Transmit Power: 100%

5Ghz

  • Channel set manually
  • Mode: 2400 (Max)
  • Transmit: 100%

Both WPA2-Personal[AES]

 

LAN Setup:

  • IP Address: 10.0.0.1
  • IP Subnet: 255.255.255.0
  • RIP Direction: Both (Default)
  • RIP Version: Disabled (Default)
  • Using Router as DHCP Sever (10.0.0.2 - 10.0.0.254)
  • No Address Reservation

QoS Enabled (But also works terrible)

Re: WiFi connection Unstable

So that I understand 10.0.0.7 is being assined across two different MACs ? Check that...7 isn't static on a client and within the DHCP scope. If so reduce the scope or set the client to DHCP assigned. 

but mostly just a guess as the logs don't show much.

Re: WiFi connection Unstable

Sorry I wasn't more specific;

This is just small fraction of the log. It extends to a lot more. I have around 6 different wifi clients. All get the same problem. Some connected via 2.4GHz, other 5GHz.

Later I will backup my settings and restore to factory defaults.

Re: WiFi connection Unstable

Also to answer your question, each MAC Address is being assigned it's own IP address (always the same IP).

Re: WiFi connection Unstable

Hmm might work. Sounds like the dhcp setup. other thing I’ve seen in the past is firewall blocking the incoming final dhcp ack request which is on a different udp port rather than the broadcast discovery messages.

Hope you get it fixed.

Re: WiFi connection Unstable

Unfortunately the issue persists. I only changed the SSID name and Password. The rest is pretty much default.

Not sure if this helps, but I also have a very low bandwidth speed on a notebook (15-20 Mbps on a 100 Mbps connection), while standing right next to the router. Wired works perfectly.

Re: WiFi connection Unstable

Couple of things to try

1. could you go to the ...3 client and (assume Windows) run "ioconfig /all" in a cmd and post the info. (Scrub the MACs before posting if you want)

2. Just noticed you have smart connect working. Always had issues with that feature,  could you disable that and see if it works?

 

are those the only logs you get ? Still leaning in the DHCP lease time direction. The times differences in the logs look to me like the renewal reservations. But a massive guess

Re: WiFi connection Unstable

Also noted that you've gone from private class a to class c ? Are you looking at a different network or has your ip config changed.

Re: WiFi connection Unstable

I've resetted the router and the problem persisted for some time. Suddenly it stopped and hasn't returned.

 

I do still have an issue with the WiFi bandwidth. It seems to run very slow. In the settings I've checked that both are set on max (600 Mbps 100% on 2.4 GHz, and 2400 Mbps 100% on 5 GHz). Guest WiFi is disabled.

With an internal network speedtest (iperf to a local wired PC), I only get around 80 Mbps.

iperf Done.

Note that 192.168.1.3 is a cat6 connected PC.

 

I should get at least 550 which I had on my previous low-end router. I've enabled/disabled some WiFi settings (AX, Smart Connect, 20/40 Coexistence) but nothings seems give a decent WiFi speed for this "high-end" router.

 

Should I return it for warranty? I've made this speedtest short after I've resetted the router (minimal settings adjustments done).

Re: WiFi connection Unstable

I just realized this is a known issue:

 

Why does the WiFi feel slow on my NETGEAR Nighthawk AX4? 

 

This is really disappointing. Is there still no fix even one year after being acknowledged that this is a software issue?

Re: WiFi connection Unstable

Is "Enable MU-MIMO" unchecked? I noticed speed issues when it was checked.

 

Also, in lieu of using Smart Connect, I just name my 2.4 and 5 networks the same name so that the clients can decide the best network.

 

I'm still on FW V1.0.1.70_1.0.30
