Wifi is sloooooooowwww

[ineedacab]

I have a Samsung S7 that I run the wifi on at home. I have a Motorola 16x4 High-Speed Cable Gateway with Wi-Fi, 686 Mbps DOCSIS 3.0 Modem, AC1900 Wi-Fi Gigabit Router and Power Boost.

My network service is through Straight Talk. When I'm at home and on my wifi, my phone apps are sloooooow. Like so slow it takes them about 15 or more seconds to load pages. My Speedtest takes forever to load up as well, but when it does, it shows I'm getting on average over 90 Mbps.

When I take my phone off the wifi, all problems go away. My laptops on the network run fine with no issues and no lag. It seems to only affect my phone. It started after I installed the Motorola. I was using a Netgear N750 wireless router.

This seems to be an issue on both my 2.4ghz and 5ghz networks and seems to affect accessing the internet through my apps on the phone the worst. (problems are still on the browser too) I have wiped the phone and reset it to no avail.

Any ideas on what can be causing this or how to fix it? Maybe my wifi chip is going out on the phone?

******* ALSO my WiFi symbol on the phone doesn't exist at the top of the phone anymore to indicate it's on. It just disappeared. I'm honestly wondering if something screwy is going on with the wifi chip.

Edit: example: 240.46 Mbps download on my phone just now. This is through the Motorola plugged into the old Wireless N750 wireless router. That literally cannot be right, with the new Motorola by itself, I'm only getting around 90 usually.

edit again: now I'm getting 79 Mbps on the wifi with just the Motorola. Apps are still slow though.

My Speedtest takes forever to load up as well, but when it does, it shows I'm getting anywhere (depending on the day) from 33 Mbps to over 90 Mbps.

That might be an indicator of a latency issue rather than a bandwidth issue. Using a browser on your S7 go to:
https://speedof.me
The primary result will be the bandwidth speed but there will also be a latency number. Do the same on one of your laptops. (Same as in both using a browser and using the same test site. Using different test sites, or using an app for one and a browser for the other, introduces unnecessary variables.) If you're getting widely different numbers that might indicate there is an issue with your phone, if they're relatively similar than maybe there's a setting in your Motorola modem or AC router. Also, one thing you should clarify is how you have those two configured -- if both have DHCP enabled that will be one big problem. One or the other should be your primary gateway, having two DHCP servers on one home LAN is generally a bad thing unless they're specifically configured to be managing to distinctly separate networks. One or the other needs to have its routing functions disabled, so one is the router, the other just a switch. If that is how your LAN is set up, try installing this network analysis app, Netalyzr on your phone and let it do a scan of your network:

The end result will show a pretty extensive rundown of your network and often some possible suggestions that you might be able to implement in some random setting in your modem or router.
Also, is this slowdown just on your home WiFi? Have you tried using WiFi elsewhere and it's also a problem?

Just to be clear, when your S7 is using WiFi that slows down your entire home network?

No, the internet is not slow on my laptop or desktop when I use my phone. It's just my phone runs like molasses when it's connected to the wifi. I tried downloading some apps through the wifi and they froze while downloading today. I tried again through the phone network and they went instantaneously.

I'll run some tests using the links you gave me and report back to you!

I ran the test and have the results ---- what would you like to know from it so we can identify this issue?

If you're latency numbers are significantly different than running a test using Netalyzer might indicate an issue with your modem or your router that you can correct. I'm still curious about your home network set up though. If both your modem and router are doing their own routing functions do you have one SSID or two? If two, are their channel setups on some 'auto' setting or do you have two separate specified ones? You might also want to be using different local addressing to save on confusion -- one 192.168.x.x and the other 10.0.x.x for instance. If one, all routing functions need to be disabled on either your modem or router (leaving one to be your sole gateway), and have the Ethernet cable running into your router using one of the open LAN ports, not the WAN port.
