Hey

So the router works fine and delivers the suggested speeds but when I try to download large files, the internet stops working for that device but the device is still connected to the router and all other devices work normally and have internet access.
For eg, when I try to download a game on steam of large sizes, this connection problem occurs but there seems to be no problem when I try to download through a LAN cable. Please suggest a fix or else I will be returning the router since it has been only a few days and I have exchanged it once already.
