Hello,

I found that the internet speed decreases too low when my friend is connecting to the wireless router. It came to our notice last week. I tried restarting the router, plugged and unplugged the cable, but it didn't help. My router is Linksys EA6900. I am using the cable internet of Acanac. I get internet speed of 15Mbps speed. We haven't done any updates in our system or the router. I hope, I can get a fix for this problem from here. Please give your suggestions to troubleshoot the issue.

Please help

I didn't find the right solution from the internet.
