2400mw in at the port does not mean 2400mw WiFi output.
Yeah, you're right! well my mobo is old but has USB 3 which I used it most of the time for the wifi USB adaptor in case it was better
so I should go for PCIe card, right?
That router is a very low end wifi6 router it will not perform much better than wifi5 (802.11ac). Don't believe vendor test they likely were sitting on top of the router and in a room with no interference. Most people do not get much more than 300mbps just like wifi5. If it was a top end wifi6 router it might get 600-700 sitting on top of the router. It is using what is called QAM1024 data encoding and you are lucky if that works 5-10ft from the router.
You can't look at the power coming from the usb. That is powering the whole device. When you look at it that way you could say a computer that has a 800 watt power supply would put out 800watts of wifi. It would actually fry you sitting next to the computer. 2.4ghz is exactly the same frequency a microwave oven uses and many are only 500 watts.
The only numbers that matter are the ones I linked for your device. These numbers are verified by the FCC following very strict rules on how you test.
Unless the device is illegal they can not put out more than 1watt of power. Things like alpha and amped like to pretend their device and put out more power but when you look up the FCC numbers they are under the 1watt limit. Its not like the unknown brands from china that do not have fcc certification. The only way to get those is to import them yourself since customs does not care to enforce fcc rules for 1 device but if you imported a few thousand they would block the shipment if there was not fcc certification.
I thought the higher QAM the better from what I saw in that data sheet? the numbers were getting bigger going towards QAM 1024... I guess I didn't understand the sheet.
I understand what you say, in the least I thought it can provide 2400 watts if the wifi adapter needed it, like any device it can consume low watts or high watts depending on settings and you need the port to be able to give enough power if needed.
I honestly never understood how they control the power output, I always thought by changing region you would do that, I mean every country has it's own rules, or do they make special batches for USA that is complying with US rules for example? or do they use driver to control the output and block it in settings, I always searched this topic without much results. I just remembered that looong time ago I tried changing Tx power using Linux commands but it didn't work either (I think), for windows I don't think I managed to find a way.
According to Tplink site mine works at 20dbm in CE standard countries and 27dbm in FCC countries which is what it does in the tests (26 point something) but how much USB power is need to output that? is there a formula for that? my guess is 2400 mw is enough, it can't be less efficient than that. (2400 to 400)
I searched FCC site for Alpha networks products, they don't seem to have shipped anything new to USA.
Also found this
FCC rules , it seems the more gain antenna has the less power is allowed to output? did I get that right?
So what router would you recommend from the list as minimum? what would you point me to look at?
Technically they aren't lying, just being deceptive and allowing the consumer to make assumptions based on their own ignorance of the technical details. On their website, it clearly states 450mbps wireless speed numerous times, but doesn't say anything about internet speeds or lan speeds.

It is technically capable when doing file transfers to several computers from wifi to LAN.
OP needs to buy a better router for their internet plan.
The public is always ignorant, that is no excuse to take advantage of them, just like food labels, they always try to make it clear and simple, why not in tech products? it's like only IT pro buy routers, no mom and dad buy them too or should be able to do so.
Like selling a car that can reach 300 mile/hour with small print saying tires explode after 200 mile/hour lol this is totally a scam, I can't replace that port so how can I fix it? I can't.
I don't get how that 450N router is 50 JOD and the AX10 is 45 JOD. I'd get the AX10 for that price.
That's why I think I still have time to sell it, don't know why the price is high, maybe performed well?
After reading your reply I thought what about the TV built in wifi, it seems to be wifi5 but couldn't exceed 55mbps when the router is in front of it, weird!
I got my wifi adaptor out again and I am seeing the tplink router showing up and disappearing and having problem connecting to it on windows 10, no problem with nokia extender, this reminded me why I didn't sell it last year, I feared it is broken, seems to be working fine when connecting from win 7 but not very sure.
