Mediatek MT7921 Miracast Problem

turktiger
Level 7
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,
Are the bios version 315 and MTK driver V3.00.01.1207?
Did it occur while connecting to 2.4G or 5G wifi?
Thank you.

Hi turktiger,
Because bluetooth may work on the same wifi 2.4G frequency, they may disturb each other when you use wifi 2.4G.
To avoid the interference, please use 5G wifi instead when you use bluetooth.
Thank you.
