[SOLVED] PC gets very low Wifi speed than tablet and phone on the same access point

[jaxx199]

Hello,

I get very low wifi speed on my pc compared to my tablet and phone on the same wireless access point

destop = 5-50 Mbps
tablet = 200-300Mbps

My desktop uses a wireless usb wifi adapter
TP-Link Archer T2U AC600 Wireless Dual Band USB Adapter for PC, Desktop, Laptop and Tablet (Supports Windows XP/7/8/8.1/10, OS X (10.7–10.10), USB 2.0, 600Mbps WiFi Wi-Fi

Tablet= Mi pad 4 plus


so can anyone help?

i ordered this today

TP-LINK AC1300 Archer T3U Plus High Gain USB 3.0 Wi-Fi Dongle, Wireless Dual Band MU-MIMO WiFi Adapter with High Gain Antenna, Supports Windows 10/8.1/8/7/XP/MacOS


will this help ?

Thank you.

You can try and reinstall your chipset drivers and then try reinstalling the wifi adapter's drivers. Make and model of your wireless router? You will need to check and see if the router you're working with is pending any firmware updates. As for your platform, what are the specs to your "build"? If it's a desktop, please state the specs to the build like so:
CPU:
Motherboard:
Ram:
SSD/HDD:
GPU:
PSU:
Chassis:
OS:

Often times a bad line of sight between the wireless adapter and the router is what can cause poor signal strength and subsequent reduced speeds. As for your lower part of the question, it's a good idea to ask first and then buy later as opposed to doing it the other way round.

If the first adapter is the tiny one with no external antenna the new one you purchased should be better. The larger antenna is going to make a huge difference. The case blocks a large amount of wifi signals.

On both I would still use a USB extension cable so you can move the device away from all the metal in your computer case.

WiFi is just radio. As such it has the same constraints as two walkie talkies working together. Two devices can't be accessing it at the same time, mush less three. Here is an excellent article on using WiFi: https://arstechnica.com/information...hat-a-deep-dive-into-why-wi-fi-kind-of-sucks/

The point is: use a wired connection when possible.

The one thing I always check first is to connect the PC via ethernet and run the test.
That'll give you a better idea of best throughput.

more antennas your device and router has, better speeds you get
well anyway, disconnect everybody from your wifi, and connect just your PC...whats your speeds now?

The T3U doesn't appear to be any different than the T2U you already have? They have the same form factor.

Those little wifi dongles aren't very good, they generally have poor range and are prone to USB 3.0 power interference.

If you have a desktop, I would either get an internal PCIe wifi card, or buy a router that can be used as a wifi bridge. A router will have full size antenna and actually more antennae to connect to the main router. You would then use an ethernet cable to connect to the router bridge. Certain asus routers like the AC56u, 66u, 68u, 86u, all have media bridge mode. It's really easy to set up in their routers.

It would be nice if tplink used different actual part numbers.

Both the t2u and t3u have versions with external antenna when they put the word "plus" on it. If he really did order the plus it will have a antenna. It is a very strange device the somehow put 2 antenna inside 1 physical antenna.

I agree the pci card would likely be better but since he already ordered something before he asked it may be problematic.

i don't have a long enough cable.

my router is the default router provided by the wifi company and it's a huwaei router. I will check the new adapter, but if it didn't work I will look into the PCIE cards.

I am the only one using my Wifi.
It's just that the reception on my desktop PC felt wonky, sometimes youtube videos start playing in 144p with high pings in games.
but on my android tablet I get fluid video playbacks and speedtest show way higher speeds.

 

[jaxx199]

i will inform you guys tomorrow. I should be getting my new adapter tomorrow.

 

[jaxx199]

update-

Got the new wireless adapter today. It has an external antenna.

Speeds

Old adapter - 5-50 Mbps
Tablet (Mi Pad 4 Plus)- 80-100 Mbps
New adapter- 150- 220 Mbps

Just one more question
the new adapter is covered in plastic covering.
Should I remove the plastic or does it make no difference?

Thank you to all those who replied.

Yup those tiny little adapters and the tiny antenna are junk. They are designed for things like table or laptops that for some reason need a wifi. On portable device the small size is more important that performance.

I guess it depends on what plastic, if it is some kind of very thin clear tape I would remove that. These device get fairly warm and heat can damage them so anything you can do to reduce that. If it is going to be hard to remove then I suspect it is not meant to be removed.

yes, it's the regular transparent plastic film or tape with which new items are covered.
