This is extremely odd. I'm having the exact same issue with one of the new inspiron 7577 gaming laptops. I don't get anything over 1.5MB/s download speed and have tried literally everything. I'll be contacting support tomorrow and if the issue isn't resolved the laptop will be going back unfortunately. I run an online business and need constant high speed access to the internet. Totally unacceptable in my opinion.
Had the same issue, since buying a new 7577 a few days ago, finally found a solution, what fixed it for me was
System Configuration - sevices - and then uncheck SmartByte network service
So having got my download speed up to scratch, my question would be, is there any downside to unchecking the SmartByte network service box ?
I had the same issue with my Inspiron 5000. The solution from Philrat64 worked a treat. I also uninstalled Smartbyte to make sure it does not reappear.
Wow, you rock! Thank you so much for the solution and all Dell offered was stock language about 'speed will vary'. It is amazing that Dell would install such broken software and even more amazing that they have not fixed it by now. Another reason to do stock!
Thank you again very much.
Thank you. I did not find SmartByte there on my Dell Inspiron 15 3000. I did find it in services. I stopped It and disabled it my speed jumped from 530kbs to over 100mbs. Then I went further and uninstalled it. Dell did not post this in their info. Funny how they did not.
