Windows 10: Wifi Speeds Slow on 1 PC on network.

Good morning all,I noticed my sons PC was much slower than the rest of the computers in the house, he's using Windows 11 and has a TP Link WN881ND Wifi card which is Wireless N and should be capable of speeds up to 300mbps, however he's getting around 50 max, I can get around 350 on my phone / laptop etc.One thing I noticed is when I go into the adapter properties in Wireless mode I only get options for 802.11b and 802.11b/g the N seems to be missing. I've updated the drivers from the TP Link website and tried removing and re adding etc with no luck.Any advice would be most welcome.Many than

:)

 

Slow WiFi speed on PC only

a week before the problem occurred i had just upgraded to NBN and was fine for the first few days then every device in the house slowed down after this was fixed the PC was the only device that still had very slow speeds.

Since every device was working fine with NBN and the PC was the only device have WiFi Problems i thought the Problem was with the Network Adapters so i tried using a Ethernet cord and also buy a different Network Adapter all of these solutions did not work
and still had very slow speeds.

Currently the PC speed is 0.25 mps download and 1.09mps upload while other devices are reaching speeds of 44.3 mps download and 17.1 mps upload.

If anyone has and ideas of how to fix this problem it would be much appreciated

Update your drivers and BIOS/UEFI firmware from PC or motherboard maker's Support Downloads web page, using the full model number, Serial Number or Dell Service Tag on sticker. Compare the latest drivers available for download with the ones presently installed in Device Manager reached by right clicking the Start button. Make sure you have the latest BIOS or UEFI firmware, Chipset, Display (Video), Sound, USB3, Bluetooth, Network and all other drivers, or else download and install the latest now.

Updating drivers from the Device Manager or Windows Update is rarely enough. The most basic thing we need to learn to maintain a PC is keep the latest manufacturer's drivers installed from their Support Downloads web page.

If you have the latest network driver then try on it's Driver tab also to Roll Back, or Uninstall and then restart PC to reinstall the driver. Try also all older drivers from Update Driver > Browse > Let Me Pick list working backwards.

Go to Device Manager > Network Adapters, select Wifi adapter, then Power Management tab, clear the check box to "Allow the computer to turn off the device to save energy." Then on the Advanced tab disable any energy-saving options.

Enable IPv6 in the network adapter settings:

Run the fixit from Configure IPv6 for advanced users - Wig:type (Re-enable IPv6 on all nontunnel interfaces) and reboot.

Right click the network icon in System Tray at bottom right end of task bar to Troubleshoot Problems. When prompted choose Wifi to troubleshoot so it doesn't report cable unplugged.

Go to Settings > Network & Internet > WIfi > Manage Known Networks, highlight and remove the network having problems, restart PC to see if it shows up again.

Try plugging in by ethernet cable to the router to compare, then plug the ethernet cable into the modem (if separate) to see if this might be an issue with the router.

Try powering off modem, router and PC and then restarting in that order with 1 minute in between each. You may need to reset your router or even optimize it following these steps:

Your router manual is always available from the manufacturer's website for your exact model.

You also are entitled to Support from your internet provider to get online on all devices. This is always included in the monthly bill. If your router is less than a year old they will also Support getting it connected and optimized.

Another option is you could replace the wireless adapter with an inexpensive USB nano adapter like this one:

If nothing else works then do a Repair Install, by installing Media Creation Tool, open tool and choose to Upgrade Now. This reinstalls Windows while keeping files, programs and most settings in place, and is also the most stable method to advance to the latest version: https://www.translatetheweb.com/?ref=TVert&...
