WNDR4500 denies Samsung A33 to access

Hi all!

I'm having trouble with my WNDR4500 router and a Samsung A33 phone that the router keeps blocking.

The router is set to block all new devices.

When I check, I'll find the A33 device/MAC-address as blocked.

I can set it to be allowed, but after a few seconds as allowed, it toggles back to being blocked again.

If I turn of access control entirely, the phone can access without any problems.

 

As said, it is an older WNDR4500 (model year 2012) running firmware V1.0.1.46_1.0.76

The phone is updated as far as it is possible,

I'm using the "real" MAC-address of the phone, not the ficitve MAC-address created by the phone, however, I've tried with both without success.

 

Any ideas how this can be resolved?

You have done well to keep your decade old router alive.

 

Does it save logs that can tell you anything about the events that prompt the router to refuse access?

 



The router is set to block all new devices.

Can you get in if you clear that toggle?

 

You could also try a reset on the router to see if that helps. You can always tell the router to block new devices again.

Even that firmware is five years old. There comes a time when the technology has moved on so far that it is wise to move on to something more modern. The N900 wireless technology on the WNDR4500 is seriously ancient. Netgear stopped using it as a sales pitch in 2015.

Thanks for your response.

 

Yeah, it's an antique, but so far I have had no problem with it when addning modern gadgets. 🙂

 

I've looked in the logs but nothing there stands out as a possible reason.

 

If I clear the toggle,he phone has no problem to get access to the network. There are some other strange things that I can see in the router.

 

I tried to give the device a fixed IP-address tied to that specific MAC-address. But even if I have this, the router still assigns a different IP to the same MAC-address when connecting.

The phone has two MAC-addresses as far as I can tell. The hardware MAC; "the phone's wi-fi" and a random MAC changing every 24h. I'm not sure if the router can hadle this? On the other hand, a new iphone 13 which also uses random MAC can connect. Might it be an Android problem?

 

Also, I'm thinking about WPA2/WPA3 compability. Can this cause something..?

Some of the newer phones are using random mac/ip addresses to connect with. It causes issues with these types of setups. Sometimes you can disable it on the phone. Have you checked on your phone?
