I am using the Dell G7 laptop, with an Intel i-7-8750H processor and a dual band 9560 card.
On my 5.0 ghz wave, I am getting upload speeds of 400+ mbps but my download speed is capped at around 70mbps. My download is capped at 70mbps regardless of whether i am connected to the 2.4 ghz or 5.0 ghz wave. I should be getting at least similar download speeds relative to my upload speed, but this is not the case.
Never seen this before.
Methods I have tried to mitigate the problem or verify what the problem is.
Verifying whether it is a router problem:
1. Used my Galaxy S8+ and connected to the same 5.0 ghz wave. I obtained around 360mbps download and 300mbps upload.
Verifying whether it is a laptop hardware issue.
1. Connected my Dell G7 via a Cat 6 ethernet cable through the ethernet port. I received download speeds of around 950 mbps, indicating that the laptop is capable of such speeds. Naturally, using a wireless connection would yield slower speeds, but 70 mbps is bit too small.
Seems to be a problem with the intel wireless 9560 card. It is baffling that i am getting upload speeds 7-8 times faster than my download speed.

Link 2: With Cat 6 ethernet cable LAN connection
ALL download/ upload speeds were measured using Ookla Speed Test.
