Mediatek MT7921 Miracast Problem

[turktiger]

I ve bought a new asus rog g513ih with mediatek MT7921 wifi card but everything is problem with this card,

- Very slow download in different wifi channels, very fast in some wifi channels (fixed this with new driver, fine)

- Sometimes connecting with miracast or widi sometimes not to tv (confused) changed modem router it's same tried to change ax to ac nothing changed

- All connections are full of lag with all drivers containing the given one in this forum

- I ve LG tv , tried TV 2 old computers they are not lagging freezing or nothing everything is fine

- I dont think this problem is only with my wifi card, read lots of topics problems with this card


Any fix for miracast widi ? My old phone can but new computer cant do it lol

Hi turktiger,
May I have the bios, wifi driver, and Asus MultiAntenna Service version?
Do you connect to tv directly or through a dongle?
If you adjust wifi channels to other channels in the router settings, are miracast and widi connections still lag?
Thank you.

Hi STARRAIN thanks for your reply,

I don't have Asus Multiantenna Service Installed there is no such an app in MyAsus Drivers,

i connect Laptop directy to LG Tv via Miracast or Widi, Widi connection is full of lag, Miracast connection is lagging in 30-60 seconds, yes i've tried with different wifi channels but still lagging (1 to 13 2.4 Ghz) (1-54 5Ghz) or oto channel mode not fixed.

Bios v312 latest

Wifi Driver 3.0.1.1198 (16.08.2021) - Tried given one in forum 3.2.xx not changed,

Win 10 / 11 updated ones not fixed,

This thing is making me crazy and i'm very confused, dont know what's causing to this problem, down up is fine but i wanna watch movies with pc to tv can't ?

Hello dear friend, i can see all details via pc the attachment above, the other drivers are given in this forum problematic Mediatek Topics

Tv is LG UJ630V (No problem with tv i ve tested with 4 pc until now)

i ve already said i have tested with all drivers containing yes with this too V3.00.01.1100

And dont know what to see with video its full of lag nothing to see without this

I don't think this thing is just for me I feel like a beta tester Isn't Asus not supposed to fix this problem, I've already tried everything you can ask, do you have a solution?

I want a driver without errors lags etc ? Do asus have ?

"All my trust in Asus was destroyed by a stupid wifi card" "I don't think I will buy an ASUS product after this time."

Hi STARRAIN

Are Modem Ports Open : YES
Firewalls Are Closed: YES

Are u updated Windows: YES
The Driver i ve using: 3.0.1.1100 Downloaded From Official Asus Website
The Other Drivers: YES they are all official and latest ones
BIOS: 312 Latest
Asus Multiantenna Service: 3.1.3 latest

There is no 3rd Party Aplications in PC

Everything is original updated still lagging ???

The other old pcs are not lagging same network same modem same TV

Asus Rog Strix still lagging with different TV 's and modems and different WIFI channels


The only problem is WIFI Card but not electronical, problem is Card's driver,this card is not stable and not working properly, everyone knows
