Internet speed 5 Mbps on PC, 150 Mbps on iPhone on same network

loup93 · Jan 13, 2018

Lenovo ideapad U430
Huawei GP8010 (I think)
Bouygues Telecom Bbox (Bouygues is my ISP so likely they are not the manufacturer but no other name appears on this unit)

Lenovo Cherry 4A motherboard
Lenovo power supply
- Make and model of USB or PCI Wifi adapter
- Operating system and driver version

ISP: Bouygues Telecom fibre.
Three devices connected to this network

I've been experiencing very slow internet but only on my laptop and not on the other devices connected to the network.
When I run Speedtest from my laptop I get avg d/l speed of 5 Mbps. My phone gets 100-150 Mbps consistently.
I have run the various onboard Microsoft troubleshooters and they all tell me everything is great.

I have tried looking for troubleshooting techniques elsewhere but search results are crammed full of advice to download shady-seeming apps.

This looks promising. Thank-you sir. I'll give it a shot.

Alright it seems to have bumped me up to 25 Mbps. Still not great.

Should I be replacing the network card? It's not exactly satisfactory if I can't use wifi and BT simultaneously.

It seems more like driver issue than hardware. Yeah i think you can swap it for better one, just be sure to buy same form factor soo it can fit.
But before all that have you tried other drivers or dedicated software?

Yes along the way I updated drivers with some MS tool that monitors and updates drivers. Don’t recall the name of the tool. But that didn’t make a difference. I’ll try manually updating everything.

Thanks again.

OK I manually updated the driver and it's definitely not helping. I've found others who seem to believe this is a hardware flaw with the adapter and have upgraded:

Since it seems the original card is kaput I'm now wondering if I need to swap out the card for a better one or if I can get good performance with a WiFi dongle. Anyone able to enlighten me on that issue? The laptop has a USB 3.0 port which I understand supports up to 300 Mbps.

TP link just don't, i recommend this https://www.amazon.com/Wireless-Adapter-867Mbps-Strength-Buffering/dp/B01FOHJAY0?SubscriptionId=AKIAINYWQL7SPW7D7JCA&tag=aboutcom02lifewire-20&linkCode=sp1&camp=2025&creative=165953&creativeASIN=B01FOHJAY0

I had looked at that one in fact. And this one for a third the price https://www.amazon.com/Panda-Wireless-PAU06-300Mbps-Adapter/dp/B00JDVRCI0?SubscriptionId=AKIAINYWQL7SPW7D7JCA&tag=aboutcom02lifewire-20&linkCode=sp1&camp=2025&creative=165953&creativeASIN=B00JDVRCI0

But if you're saying the NET-DYN is the winner that's what we'll go with.

Thanks for the help. Much obliged.

The problem is i don't trust other wifi dongles is cause of driver issues, i had cheap 1$ nano wifi and i worked 2h to get it working and then died on me, and same for tp-link (not archer series) wifi drivers are horrible.
