Zyxel EX3300-T0 - Issues connecting WhatsApp / Facebook / Speedtest / Smart TVs

LVRPA

Hi, we recently installed Zyxel EX3300-T0 routers at one of our campsites which have P2P links back to a main basestation. If you plug directly into the P2P you don't encounter any issues like this but as soon as you are on the WIFI of the router we have the following issues:

• Smart TVs (mainly samsung) will not connect to the WIFI or resolve an IP ( tried manually)
• WhatsApp loads but doesn't let you do Video Calls (same for FaceTime)
• Facebook has stopped loading
• Speedtest don't work.

The DNS settings are 8.8.8.8 / 1.1.1.1 - happy to share other settings we have on the routers but there should be no reason why this is occurring as there is no blocks on the services.

Any help ASAP would be greatly appreciated.

Thanks

Maybe you can contact your ISP for help with these issues, and consider upgrade to the latest firmware to see if there are any issues.
