Hi,

For some reason my laptop (Dell Inspiron 7577) has been lagging out when it comes to streaming videos online, so I ran a Google speed test and it is only getting under 10 megabits per second:

When I run the same Google speed test on my smartphone (Note 8) I get 87 megabits per second, so the issue must be with my laptop.

I have tried all the obvious things such as updating drivers, rebooting my router, etc - but it always stays the same.
I have tried the speed test using both ethernet cable (Cat6) and the WiFi adapter (Dual Band AC) but I still get the same result.
When I check the Network performance in the task manager it fluctuates between 4mbps and 10mbps.

I have obviously googled the issue and most people blame a faulty ethernet cable or faulty NIC, but I know the cable isn't the issue as the WiFi on the laptop has the same result.

Does anyone know what could be causing the issues, and can anyone advise any steps I could take to fix this?

Many thanks in advance!

Jon
 
I didn't actually try a different browser! I will try that shortly.
I actually cancelled my Kaspersky subscription the other week and it's been slow since then... I will also try disabling that too.

Thanks for the quick reply, I knew I was overlooking something!
 
Ok so...

I used a different browser (IE, rather than Chrome) and that didnt make a difference.

I made sure my duplex was set to Auto (it was).

I disabled my AV - no change.

I rebooted into safe mode with networking and got 108mbps download! Eureka!

However I guess I don't really know what the issue could be as I have rebooted out of safe mode and now I'm back down to < 10mbps! Booo!

Any ideas what I should do?

Many thanks.
 
I disabled all my apps on startup then rebooted - no change.

I have also run the Network Reset, but that also made no change (in fact the first time I ran the test I was down to 5mbps, but it went back up to 10 the 2nd time).

I also followed a guide online to optimise my network adapter (before the network reset) to ensure there were no power saving features enabled - but this didn't help either.

Nope - sadly not:

Although... good news everyone, we seem to have resolved the issue.

I downloaded ccleaner and avast and scanned / fixed all - and also went through and unstalled any apps where I didnt know what it was.

Rebooted and now I'm getting my full speed again!

Thanks everyone for your help, you've saved me from days of frustration! :-)
