|
 |
Hi all, I hope someone can help me wtih this as I am stumped!
I have always had PC's and had no issues with my wired connection.
I recently bought a laptop and was using it on Wi-Fi, which i got about 70% of the connection speed I got with my wired PC connection, my router is pretty shite so its probably this.
Anyway, the real issues arise when I use a wired connection on my laptop, the speed knocks itself down to 100Mb, after a lot of messing about i did get the full speed for about 3 weeks, then had to fully shut the laptop down, and it reverted back to 100Mb
Exactly the same set up as my PC, same cables, same router, same everything, but the speed keeps knocking itself down to 100Mb
I hope you can help, these are the things i've tried
Laptop is running on Win 11
Tried a differenct cable in case the laptop does not like it
Tried removing the card in control panel, reinstlalling it etc.
Gone through every network setting on the laptop
Reserached thourougly to see if others have similar issues, all the answers state it is the router or the cable (it's not obviously)
No setting is throttling the connection
I'm not an IT novice but this has me stumped, why would it gain full speed with exactly the same settings/cables/router for a few weeks, then throttle itself again?
All the settings are identical, nothing changed, and as I said it did gain full speed for a while, but after a shutdown has throttled itself to 100Mb.
Any help would be appreciated.
Thanks

Win11 gone crazy? Only reason I can think of that stumps even the nerdiest of nerds. Try dual booting another O.S and see if issue persists. Telemetry can mess with shit constantly from experience.

I too suspect Win11, I should have mentioned I also disabled my firewall/anti -virus for a bit. I have tried everything.
Honestly i have been at this for a couple of weeks now and all suggested solutions point to cabling/router. But its not those, as soon as I boot up my PC on exactly the same cabling/router I get full speed. PC is running Win 10
It does obviously work as I was getting full speed for about 3 weeks, so its not an issue with the network card in the laptop etc. It must be a Windows setting/registry issue
Good idea about the other OS I could use a Linux boot and see if that works at full speed
Cheers

Have you already tried bypassing your Wi-Fi router and connecting directly to the CPE installed by your ISP? Just to get the router completely out of the equation.

Forced 1000 Mbit in drivers/router?

Had not exactly the same but related problems on a couple laptops.
After sleep or long idle NIC would switch to a permanent "Cable Disconnected" state. Only power cycle would enable it again till next sleep or long idle.
New BIOS resolved the problem. But on older laptops without new BIOS, disabling Power savings features for the NIC also resolved the problem. Band-aid solution but it worked.
Device Manager --> NIC Properties --> Power Management
Uncheck "Allow the computer to turn off this device to save power"
Device Manager --> NIC Properties --> Advanced
- Disable everything with "Green" / "Eco" / Energy Efficient Ethernet (EEE)
- Check for "Auto Disable Gigabit" option and disable it

Hi guys,
Thanks for the replies, I have tried all the suggestions you have made, as I said it is fiune on my PC, with exactly the same cabling, router etc.
BIOS is up to date, no power saving option is on the net card, as I said I have tried everything and as i also said it did just 'work' for about 3 weeks until i had to shut the laptop down (usually on hibernate), so I know it definitly can get 100% speed, so there is nothing wrong with the cables etc.
It just chooses to knock itself down to 100, all setting are correct, I have checked and re-checked

Had some weird issues with my wifi, downgrading the driver a coupler of versions back to a stone-age 2020 driver did the trick (while introducing another, but very minor issue  ). Your case is with the ethernet NIC, but have you tried that?

Same think I thought of pickup. Bad cable/line noise can cause a network connection to drop to the next 'tier' down for speed. But unless I read it wrong, Reg is using (or has tested with) the same cable he used for his other computer.
Does your router/modem have LED indicators of what is plugged into it for speed? Like mine has different LED colors on the plug for 100MB, 1GB, and 2.5GB when you plug something into the hub. Yellow, Amber, and Green.
If so do its show it sees 100mb?

Yes as I said its fine on my PC and my sons PC, exactly the same router/cabling etc.
I just tried a new very short cable right next to my router (not that that should make any diffeence at all, but it was pissiung me off so i thought I'd try every possible scenario)and it was the same
But oddly when I brought the laptop back upstairs and used exactly the same setup as previously it has now gone to full speed. So I'm fucked if I know what it is, one of Windows many mysteries
I fully expect it to drop to 100 again in a day or so, then I will just reinstall Windows I suppose
Thanks for the help guys

I'm out of ideas, you called a priest yet to try an exorcism?

Please list what router you are using? Do you have a separate network switch between the device and your router?
This can be router's problem as you have mentioned. Instability in throughput speed is not that rare and it can be caused by many reasons, one of them being faulty RJ45 connector.
Default settings in OS should give you full speed regardless of drivers' version.
If you can try with different port or even totally different router.
ps. Remember that router is good as long as it gets constant firmware/OS updates. If not, then you are trading 'savings' for security risks.

You should try a different network port in your router with a stable Gbit connection (PC).
Connect straight to the internet outlet.
How long is the cable between laptop<->router?
Tried a different NIC cable?
Next step would be to install Win10 to a different partition and check the behaviour. I do have a suspicion that the issue lies with OS/drivers/settings but it's difficult to say without access to the hardware.
Next step would be to suspect overheating in your laptop (overheating the particular portion where the NIC chip is located). Or suspect something else.
Final step: accept flipping between 1000 & 100Gbit or buy a new laptop.

The idea of a priest is probably the best suggestion
In all seriousness I am 99% certain it is Windows being...well Windows
Once I get a chance I'll try Linux |
Oh so you want more problems?
