Windows 10: One device much slower than others on home wifi - why?

Before I get to the extensive background on this, I'll start with a simple problem statement.

One computer on our home network gets much slower wifi performance, than anything else on the network, despite other devices mere feet away getting better performance.

Now for the background.

We had an ancient legacy Spectrum package that was rated at 20 Mbps download, and it seemed to get the job done, even with work-from-home during COVID-19, and even with lots of devices - three Windows 10 computers, as many as two ipads, as many as five cell phones - sharing the signal.

Then I noticed that the download speed on one computer, a Windows 10 all-in-one from late 2016, was atrocious. Something like 1 Mbps.

I blamed this on the legacy package and upgraded to a 100 Mbps plan from Spectrum. The new modem and router (manual at https://d15yx0mnc9teae.cloudfront.ne...ide15Apr17.pdf) arrived yesterday.

Not wanting to mess with home wifi - all those devices plus a thermostat - I connected the modem, but left my old Netgear router (WGR614v9 | WiFi Router | NETGEAR Support) in place. Yes, this router is capped at 54 Mbps, but my goal is simply to have everyone's internet working fast enough.

Everyone's download speed increased noticeably and measurably - I use speedtest.net - but the "slow" computer was still slow. Maybe 4 Mbps, once, tops, and otherwise 1-2 - once I measured it below 1.

Logically, I would think that the router position would be the reason. Router is on second floor of house, slow computer is on first floor, with one ceiling and some walls to pass through to reach the computer. But if I were to drop a plumb line from the router to the first floor, it's probably no more than six feet horizontally from the router. So call it 10 feet vertically and six horizontally.

So not only is the router "close," but a laptop in the same room, maybe 10 feet from the computer, is getting 20-40 Mbps. If the router were positioned poorly, would this be happening?

So I'd welcome some suggestions and comments about this. Naturally, it would be a fairly simple weekend project to put in the new Sagemcom router and configure the new network and get the devices working with it. But I don't want to make that effort until I can have my arms around the slow performance of the one computer. Things I wonder:

1. I never thought about rebooting the Netgear router, but much I read online suggests that a router reboot should be the first line of attack - comments? I'm not at home now, but it's possible the router has been running since the last time we had a home power failure, probably 9+ months ago.
2. Does WiFi Analyzer (https://www.microsoft.com/en-us/p/wi...otverviewtab) do any good? I assume that to use it, I'd install it on the slow computer, run it - and then what? Does it "tune" the computer, or does it make recommendations that I implement on the router?
3. I don't know what kind of wireless card the slow computer has, but are there tricks - play with the driver or otherwise - that I can try to optimize it?
4. How useful is running speedtest.net from a laptop or cell phone from various spots in a house to see the differences in router signal strength?
5. Any other tricks I can use to try to improve the WiFi performance of the slow computer? And if no, how likely am I to see it improve when I swap in the faster and newer router?

Once again, yes, I know it's stupid to have a 54 Mbps router, 13+ years old, with an internet package that features 100 Mbps speeds. And I'm perfectly willing, when I have time to do all the configuration, to swap that router in. But the at-the-moment issue is the slow performance of the one computer, as I describe.

Suggest Portable small WiFi Storage device with Maximum WiFi range

Hi Guys,

Would you please suggest Portable small WiFi Storage device with Maximum WiFi range ?

The smallest I know is this





Is there anything better than this which has maximum Wifi range? For example can it play movie from 30 meter distance ? From other room ?

Thanks.

Good day,

Refs above mail, please be inform that i have already took the following steps, to fix the same. but nothing works.

• Release and refresh from command option.

strange is that, when the issue occurs. following things observed.

• wifi driver is vanish from device manager.
• wifi laptop on/off switch light become orange means no wifi. but if i press the same button i use to see on desktop flight on and off.
  
• when i used command (prompt) i saw there was only Ethernet data came. nothing related to wifi.
