Windows 10: Sudden drop in Wifi internet speed while Ethernet speed is ok

Hello,

I'm experiencing a sudden drop of internet speed only through my wifi connected device. I use to have 200mbps on my wifi connected device but recently they have dropped down to 15mbps, tested in the same location where I got 200mbps before. I checked the speed on my wired connection device and they are running a steady 200mbps internet speed. I tried rebooting the router (nighthawk x10 R9000) but no use.

Any advice?

Thank you

:)

 

WiFi speed drops to ZERO

The WiFi speed suddenly drops to ZERO. It fluctuates between the maximum speed and zero, and then finally sticks to ZERO. I have tried almost everything like troubleshooting, Re-installing the WiFi driver, Disabling & Enabling the WiFi driver, etc. I have
also tried to connect the same network with the Ethernet and it worked fine. Is this the software issue or some hardware issue?

 

Sudden Internet Speed Drop


Hi there

Check your router (or your connection) hasn't dropped back from 5GHZ band to 2.5GHZ band -- on the 2.5GHZ band especially if there are a lot of people on the same channel your speed will drop.

If you are using LAN / direct connection check also quality of cable --degraded LAN cable can cause horrendous drop in speeds.

I've given up direct connection via LAN --am using Wifi-Internet via ethernet-->wifi bridge on an older router --still getting >250 mib/s -- however if I switched to 2.5 Ghz band this would drop to around 55 Mib/s -- BIG difference.

Note the ethernet-->wifi bridge is a great idea if you don't want LAN stuff all over the place --on 5GHZ with current ac technology max speed is 433 mib/s - so you don't lose out using this --even if you have a Gb LAN adapter connection you won't get that through the average ISP (at least not yet). You can even transfer quite large files on local LAN quite decently fast too with that typeof connection.

My connection is fibre -- all the way -- no copper / older adsl type technology anywhere - and here there isn't that much contention (around 15% of the ENTIRE population is away in France currently watching the Football !!!!!) so the difference between 2.5GHZ and 5GHZ bands is a good test as a lot of people are away not causing contention on the 2.5 GHZ band.

If you DON'T use wifi and you aren't getting the speed you are paying for - bring back the technicians to recheck your signals.

The Wifi broadband speed test works on android phone (and probably iPhones) so try that as another check too. That should confirm whether it's a Windows problem (which I doubt) or the problem lies elsewhere.

Finally check your service contract -- sometimes "Unlimited usage" doesn't quite mean that - you could be getting capped. There in tiny print (probably on page 174 of the service contract !!) might be a "fair usage" clause somewhere -- although exactly what that would mean in a Court I don't know -- would streaming or downloading and watching 3 or 4 ultra 4K HD movies which eat up several tens of GB's each be "unreasonable" !!!!

Slow File Transfer Speeds (WiFi)

Hi Ruz,

Thank you for your reply.

I have checked out all your suggestions, but nothing has so far improved the transfer speeds. To clarify the issue:

My requirement is to transfer files from my desktop PC to my laptop. The desktop is connected to the network with an Ethernet cable.

When connecting the SB2 to the network by Ethernet, the cable is connected to the laptop via an Ethernet > USB C connector, attaining transfer speeds of around 100 MB/sec. When connecting via WiFi, the transfer speeds drop to around 30 MB/sec, whether I
am using the built-in WiFi adapter or the new, third party adapter.

By way of comparison, I am achieving transfer speeds of around 80 MB/sec when transferring to my 8-year old MacBook Pro via WiFi in the same environment.

According to various internet speed test utilities, I do not have any issues when uploading/downloading via Ethernet or WiFi, which give similar results.

To summarise, the only issues seems to be the file transfer speeds when using WiFi.
