Fast internet, although terrible wifi speeds.

Hello lovely people of the LTT forum. As the title suggests, I have gigabit fiber internet in my home and bought a badass Linksys wrt1900acs to go along with it. All seems well with setup until I do a wifi speed test with my phone right next to it (both 2.4 and 5 GHz tested.) And got a speed of!.. 2 Mbps at worst and fluctuating ridiculously between 2-15-50-70(almost never)-and 5. I have not moved in the whole test and am getting absolutely poor results. I have hooked up my desktop to Ethernet and have gotten 600-900 down and up flawlessly. If anyone has ideas do let me know. Thank you for your time.

Ok. Did you try it a little bit further away?

What phone are you using?

Does it support 802.11ac?

 

Have you tried other devices to test your wireless connection?

I have to no avail, sadly.

My phone is a Samsung Galaxy s5 which does indeed support 802.11ac. This has occurred to me in the past as my ISP has provided a non wireless router/"residential gateway". Could that be conflicting with my router by chance? If so would that nessecarily be the cause of my slowdowns?

Can you show us a screenshot of Wi-Fi analyzer?

Is it next to any other wireless devices and is the wireless space congested ie are there a lot of other access points around you?  If so, try changing wireless channels.  If possible, try using another router/access point just to see if you get a speed boost.  If you do, you may have a defective Linksys WRT1900ACS.  As a last resort, you could try contacting your ISP or Linksys customer support to resolve this issue.

The 2.4Ghz will cap out around 300Mbps. You should get over 1Gbps on the 5GHz AC connection.

 

The first thing I'd do is test a LAN file transfer over the 5GHz WiFi - if the speed is optimal, then your router is fine, and the problem is with your internet connection (a service problem or something similar).
