MegaSack DRAW - This year's winner is user - rgwb
We will be in touch
I know that there's a few pc experts on here, so: I bought a new HP laptop a couple of months ago. The internet speeds were much lower than my old laptop, so after a bit of research I downloaded the latest drivers for the wireless card from Intel and, hey presto!, lightning fast internet. However, it gradually got slower and slower until it's barely useable now. I should add that when connected to the router via an ethernet cable, all is fine. Anyone any ideas?
Is laptop new or 2nd hand?
My older laptop only has 2.4GHz Wifi, got a dongle so it can use the 5GHz too and it solved speed problems.
No, Brand new. Reasonably good spec, too - i5 processor, 500GB SSD etc.
Should also have said, laptop right next to router, all other wireless devices work fine, download speed when connected with cable around 65mbps.
Open Device Manager, right-click the Wi-Fi card, pick 'update driver'. Hoof it at Windows Update.
Or, on your Intel downloads, there's a 'detect drivers' util.
Or, check on HP's downloads.
Also, it might be counterintuitive but, move it away from the router.
If it's right next to the router, why not just cable it in?
Everything else Wi-Fi in the house OK? It's not actually a router issue?
restart the router. Fixes all my wifi issues.
When kids were at homeskool I routinely did it every night.
That’s actually not recommended as your isp monitors connection stability. A disconnect every day ‘might’ lower the line speed.
You could try installing a Wifi Analyzer app on the laptop or your phone. That will show you if you have contention on the 2.4 and\or 5 bands. If you do you should be able to switch bands in your router.
If your router offers both 2.4and 5 bands it's also worth checking that your laptop is connecting to the 5 band. I have 1 device where I had to go into the device manager and tell it to ignore the 2.4 band. If you click the connection icon in the toolbar and select properties can see the details if the connection.
I had a similar problem with a new HP laptop. The "fix" for me was to turn off the dual-band feature and fix it to either 2.4GHz or 5GHz as rjmccann101 suggests. Need to go to WiFi adapter properties->Configure->Advanced to find the settings I think.
