31-40k I am in Dilemma! Should I upgrade my Present PC to AMD AM4 or AM5 or Intel LGA 1700 chipsets? Budget is limited to 40k

I gave model no of what i am using. If router is not in same room, go for one with antennas.
I have never had any issue with tp link wifi devices, so i have always bought them. 3+ since 10 years or so and all are working still.
So i haven't bought any new ones yet.

That one is less than 1k i think. Probably closer to 500.

Better options, that i would probably buy today. But i have not seen everything and these dont have bluetooth, Go as per budget and internet speed.

If router is nearby, then you can go with the tiny ones too, they take very little space and dont stick out from usb port.
I use a usb extension cable and just keep it out of view behind monitor.
I am thinking of this:

But Gigabyte B650M DS3H (4ram slots) at 10k isn't available anywhere as it's out of stock. In Amazon it's 16.5k

Since B650M DS3H and B650M Gaming X AX are same boards except for wifi/bt I think either everybody bought the normal board or all vendors/Gigabyte themselves have removed the former board while selling B650M Gaming Wifi board (2ram slots) at 10k and B650M Gaming X AX (4ram slots) at 15k
Now for me no option but to go with Gaming X AX only.

Lots of new boards, i havent check anything since i bought. Go for what looks good for your usecase.
That wifi adapter will need free pcie slot and gpus can often block them perhaps, esp for m motherboads.
I am not sure i have never used a pcie upgrade.
