Question WiFi connectivity Issues ?

[dragonfly22588]

I recently set up my desktop that has a wifi card at a new home location on the 2nd floor of a house that has AT&T fiber using an AT&T provided modem/router (BGW 320-500) which was recently upgraded from an older modem. I am running Windows 11 Home. Since I set it up, I’ve noticed that when I play games I get pretty frequent lag spikes which will freeze the game from seconds to sometimes under a minute where I will need to relog in. Less frequently during web browsing and watching videos I’ll get the same issue. However, when the connection is not experiencing a problem, everything is very fast and great. There aren’t that many devices connected to it. At most maybe 5-6 devices. When I speed test, I get good speeds like 214 Mbps download and 260 Mbps upload.

I didn’t have this problem in my previous home partly because I hard wired the CAT 6 cable directly to my computer. The wifi router now is on the first floor and when looking at my taskbar I do see 4 of the 5 waves for signal strength. I did test out my desktop by bringing it to another location and using wifi playing the same game (World Of Warships) and I did not have any problems.

Could the issue be a weaker signal and would it be improved by a wifi extender? Something like this one: https://www.amazon.com/gp/product/B08RHD97QY/ref=ox_sc_act_title_1?smid=ATVPDKIKX0DER&th=1

Is there anything else I could try to see what the cause of the issues are? If I am looking at the right type of device, can anyone recommend a good model or brand?

You changed from wired to wireless.

On the desktop did you disable the wired network adapter?

Also noted that you tested out the desktop by moving it and had no problems.

What sort of move: around the current 2nd floor, down to the 1st lower floor, etc.l?

Distance from router?

Do any of those other 5 or 6 devices have problems?
