Hi,
Anyone has issues where Whatsapp Videocall / Calls does not work? It rings on the other end but no image comes up on the other side ( phone which isn't on the wifi )
*Whatsapp videocall / call works if both phones are on wifi. But when one phone is on its own 4g / other connection then it won't work.
**Additional info : I realised that with Wifi connection via any phones, I did a speedtest via Unifi speedtest, download works fine but no upload at all. However if I use LAN cable, both download and upload works fine

QUOTE(JohnLai @ May 10 2019, 07:55 PM) Oh.....MTU issue.... First solution, upgrade your router firmware. Second solution, login to the router, Advanced--->Network-->Internet--->IPV4-->Advanced-->MTU Size--> Try changing the MTU value to 1400, 1420 or 1460 (default is 1480). Save. Pick one. EU firmware doesn't bundle TR-069. KRACK part-->If you use hidden WDS functionality to connect your C1200 to other router, then the C1200 is vulnerable.........cause the WDS part isn't supposed to be available. If you don't use hidden WDS functionality, not vulnerable. Thanks bro will give it a try. Probably if there is upload speed detected then the whatsapp issue will be solved
