Wifi issues with multiple devices [closed]

I have about 4 devices always using the internet on my home wifi network. Everything is fine and dandy until I start to do intensive bandwidth stuff like gaming and streaming movies. So I thought this was an issue with my internet speed so I upgraded to 100mbps down and 20mbps up but this hasn't improved the issue.

I have a 3 year old Linksys E4200 router. I've tried different DNS servers and i've looked for the optimal wifi frequency so that there's no interference with neighboring wifi. Because of the distance of my devices I cannot connect anything to ethernet.

Please help. My hulu keeps glitching and I can't use my laptop and xbox at the same time with out something slowing down.

One other thing is I have my xbox on DMZ would this cause any issues?

Thank you in advance for you time and help!

Solution 1:

The 100/24 Mbps are actually good numbers.

The question is are those actually arriving at your computer.

One suggestion I would make is for you to switch to 5GHz router/Network.

That should eliminate lots of neighborhood interference.

5GHz also has much higher data transfer rate between your router and your computer.

On Mac the Transfer Rate is shown in the WiFi profile and it is the one key measure how fast is your connection to the router.

My Transmit Rates are 70 on a 2.4 GHz network and 250 on my 5 GHz network.

PS, try turning off the dual frequency on your Router.

Solution 2:

Never game/stream on Wireless. Run Ethernet cable. Wireless bandwidth drops tremendously when another connection is streaming or gaming. It has to do with the way routers split or share bandwidth.
