netgear wndr3400v2 wont let new devices on wireless anymore?

[dough041]

I use my router through my comcast cable router ( bridged) and it functions fine except for a while now I can't add any new devices to the access control ? It shows them under allowed devices not connected and I can no longer get them on the first allowed/connected screen. I usually restrict it so a new device mac address needs to be input but either way anymore I can no longer get a new device to connect wirelessly? I only have approx 7 things on it cuurently...any help would be really appreciated. I just got a new TV and cant connect. I first noticed when I tried to let someone get onto the router for their phone wifi...sorry if not so clear .

Hi @dough041

Welcome to the community!

Looks like you're unable to add devices under Access Control.

Will you be able to add another device when you take one from the list?

What are the settings you have enabled on the router?

Do you have Port Forwarding, Block Sites, Block Services, USB Storage enabled?

How many devices are connected (wired and wireless)?

[dough041]

I can access the wireless on all 7 devices ( 2 wired/6 wireless). However for the last 8 months or so when I try to let family enter their MAC address to my allowed list it won't enable them to get on the wifi such as iPhones, smart tv etc. My android phone does connect but doesn't show up on the allowed list.Am afraid to hard reset router as maybe then it will not allow me to connect any new devices including ones currently on like roku, Amazon etc...

Sounds like a hard reset may be needed here.

You may want to backup the settings of your router before resetting.

Then once done, you may restore the settings.

Maybe a stupid question but how do you backup my router settings?

The link was provided in my previous response.

Thanks for the info on backing up my router settings. Although it was saved as a config file and I can't bring that up to view? 

I did run a Ethernet cable from a new TV ( couldn't connect wirelessly ) and it ran instantly. However it is not listed as an allowed / connected device. 

This has me stumped. Thanks for any ideas or thoughts. I am a little reluctant to do a hard reset as I am  concerned I would have to reconfigure all the devices connected to the router currently and I would possibly be in the position I am now not being able to add devices? At least for now it connects my iPad and roku etc....

You're welcome. The only way you can view the settings is if you'll take a screenshot of each page of the router.

The configuration file that you have download cannot be viewed. It contains all the settings that's currently configured on your router.

If you decided to do a reset then you can always get the settings back by using the restore feature.
