Fast Internet, Slow on Inspiron 15 5000

Hi everyone,

My internet's been playing up for the past 2 weeks or so on my laptop. Speedtest is saying my download speed is about 90mbps, but browsing the internet has become extremely difficult - trying to load any webpage can take up to 20 seconds, and is normally preceded by a "this page cannot be found" error message on Chrome which mentions not being able to find the DNS server.

I've fully scanned by computer 4 times over the past 2 weeks (3 with Kaspersky and 1 with Malwarebytes), I've changed my DNS settings so that it uses Google's DNS, I've tried other browsers and I've tried downloading new drivers. Nothing's come up and the problem persists, and my Internet is fine on other devices. Any suggestions on what to do?

Thanks.

I am guessing that the problem is with wifi.

How is it if you directly connect to the laptop to your router by Ethernet cable?

 

I would install new chipset driver if there is any.

I would install new wifi driver if there is any.

Windows 10 updates can wreck havoc.

Re: Fast Internet, Slow on Inspiron 15 5000

Apparently on some systems, Dell is installing a utility called SmartByte.  Theoretically it's supposed to prioritize important traffic like Netflix and minimize bandwidth to background tasks like Windows Update, but there have been several threads here reporting slow Internet performance that was resolved by uninstalling SmartByte.  Try that if you find it installed on your system.  Otherwise, yes testing with wired Ethernet (assuming your system has that) would be useful, otherwise let us know what router you use and what WiFi card you have installed in that system.  The latter can be determined under Device Manager > Network adapters.

Thank you for your reply.

I've had this laptop since the summer of last year and this has just randomly started happening, but I connect wirelessly to my network. My provider is Virgin Media.

I've used the Intel Driver and Support Assistant, which said that all of my drivers are up-to-date. Before this, I had just downloaded a new driver for the Qualcomm wireless card in the laptop, but this has not helped.

Thanks for your reply!

I checked add or remove programs and couldn't find SmartByte. I connected via ethernet and from the 5 minutes I've tested it, it seems to be working fine. It's a Virgin Media Superhub 2 and the wireless card is a Qualcomm QCA9377.

I am not familiar with the Virgin Media Superhub 2.

You may want to post on the VM forum. And see if there is a setting that can be optimized.

I really don't think this is a problem with my Internet. As I said in my original post, it works fine on all other devices.

Not sure what else there is to do.

I had a similar problem with my new Inspiron 5567 running on Windows 10.

I got decent (albeit reduced) bandwidth on high speed wifi and by using ethernet cable - but on lower speed wifi and on VPN connections the speed dropped to almost zero - often resulting in a time out error.

After struggling with effectively no internet connection for 2 weeks I finally found a few threads that mentioned that one of Dell's bloatware programs, Smartbyte from Revit could be the cause.

I uninstalled it and, hey presto, everything works.

This is a real piece of junk software and whoever at Dell thought that this was a useful addition is hopefully looking for a new job!

Hi,

 

We have the same issue on 2 x Dell Inspiron 5000 2in1's - Dell ended up sending a brand new replacement and now both don't work! We uninstalled the Smartbyte and it worked great for a day or two and now the problem is back and worse as ever. It's extremely frustrating as a service provider having to spend almost a full engineers time with troubleshooting to be sent an equally faulty product.

I'm absolutely convinced this is a software related error however the Smartbyte 'fix' was not a permanent resolution!

Hope fully Dell can assist!
