Hello,
I just purchased this Samsung Galaxy Tab A 10.1 (2019) SM-T510 tablet a few days ago and I've had strange issues with 5GHz Wi-Fi from the start.
The problem is that when I'm connected to my 5GHz wireless network and open particular apps (that were not already running or in the background), the apps have no connectivity at all and after waiting several minutes might still not have connectivity or run at a very low network speed (0-3Mbps). The apps I have experienced these issues with so far are Discord, MX Player/VLC Player (when trying to run files from local network), Firefox browser and Play Store (when downloading or updating apps).
Chrome, YouTube and Speedtest run fine whenever I'm connected to the network and start them, but Speedtest sometimes gives a download speed of 2-6 Mbps and other times 80+Mbps or more. Upload speed is always 170Mbps or more. Server does not matter. Chrome rarely shows a "website not available" screen for like 0,5 seconds before succesfully connecting to a website.
However, if I launch for example Discord in Pop-up view and then run Speedtest in the background, suddenly Discord gets full connectivity as soon as I start the speed test even though normally it would take minutes or not get connectivity at all.
The Wi-Fi settings in android show that the connection speed to the router is around 433 Mbps despite the connection working very slowly even within local network.
The issues persist even when I'm next to the router and have disconnected every other device from the Wi-Fi.
My Galaxy S7 and Nexus 7 are also connected to the same 5GHz network and do not have any connection issues with any apps and S7 always gets around 250Mbps down and Nexus 7 150Mbps down on speedtest.
However, If I'm connected to the same network on 2.4GHz, everything just...completely works. Discord, Video Players and browsers have full connectivity and speed as soon as I start them. No issues at all. Speedtest gets 40-50Mbps Download and Upload speed all the time without speed drops at all. This at least makes the device less annoying to use, but I would still much prefer to use the faster 5GHz network.
So far I've tried the following things to no effect:
-Restarting tablet and router
-Forget and readd the network in settings
-Reset all network and connectivity settings in android
-Played with Wifi Fixer app from Play Store
-802.11ac, 802.11a and 802.11n only modes in router instead of 802.11a/n/ac mixed
-Different Wi-Fi channels and channel widths in router
-Assigned a static IP
Planning on doing a factory reset on both the tablet and router later, but any help or ideas would be appreciated. Don't want to return this thing just yet.
Couple of years later, but I have the exact same issue. Did you ever find a solution?

First time poster here. I've searched all the threads and couldn't find anything on my specific issue.
Had the Nexus 10 for about a week and noticed streaming YouTube and movies was EXTREMELY slow. Slower than my Galaxy Nexus on the same WiFi network (my network speed is about 18-20 Mbps). I finally did a speed test and noticed that my 10 was getting awful results...sometimes 3-6 Mbps while sometimes it'd get up to 10-13. My Galaxy Nexus gets between 14-18 Mbps consistently. For my 10, every speed test fluctuates between 3 to 13 and it's just so inconsistent.
Now, I don't have any connectivity issues. It never drops the signal and I'm always connected, it just goes super slow to the point of YouTube videos not loading.
I'm not a wizz, but I use ATT uverse and use the router they give you. I'm not sure if it's a router issue or a Nexus issue.
I've restarted the nexus, turned off the WiFi optimization and turned the WiFi off and on. I had a ton of issues with my nexus 7 (main reason I switched to 10) and I really don't want to ship the device back to Google. Any suggestions??

For starters when you toggle WiFi optimization you need to reboot for the setting to completely turn on/off.
What ROM / Kernel combo are you using? If that is stock then it is likely the router.
ISP routers are usually cheap, they don't handle multiple device traffic very well. One thing you can do is change the stock/auto settings they come with as they are less than desirable. Lower channels/and or Auto Channel (in both 2.4 and 5 GHz), QoS, software static IP, and even Google DNS can all interfere with your router. First go into build.prop and look for the 8.8.8.8 and 8.8.4.4 lines and delete them, reboot. Try that. If issues persist go into router firmware and change all the Auto settings to a preset. Even something as simple as your phone logged on at the same time could interfere if the channel is saturated. Take everything off the WiFi except for the n10 and try that. Getting a 3rd party router with dual band / 802.11n support is ideal.
The least likely issue is that it could be a hardware issue with your n10.
So this problem has been plaguing me since I got this phone. It seems this problem is only when I'm at home on my FiOS connection via WiFi through the supplied Actiontec 802.11n router.
If I am on any other WiFi network, my connection is snappy and instantaneous. But at home, there's always 5 or more seconds of latency before a web page will start to load, or before the network connection actually starts transmitting data. I don't understand it?? I factory reset both my phone and my router and the problem persists. Oddly enough, maybe 1 out of every 20 days, it will act normal and be as fast as it should be. It's totally random and not often.
Has anyone else had problems with their Note 3 through an Actiontec FiOS router??
We recently signed up for TWC cable at home and have purchased our own Netgear C6300 modem/router. Since then, I have had a very noticeable delay in certain apps. For Google Play store, there is always an exact 15 second delay from the time I press install to when the app actually starts downloading. For YouTube, the thumbnails take about 10-15 seconds to load. For Netflix, the app takes about 10-15 seconds just to connect to my account and display thumbnails. These are the only apps affected, which seems strange. This only happens when connected to the wifi network at home from my Note 3. We have the 200Mbs internet plan and I can confirm we are getting 235Mbs when hardwired to the router and I'm getting 230Mbs on my Note 3 through wifi at the same time I am seeing this delay. So I don't see the internet speed being the problem. If I disconnect from the wifi and run on Verizon 4G LTE, there is no delay at all. When using a different wifi network with my Note 3 in different locations (work, friends house, etc) there is no delay. When using my ASUS tablet and my home wifi network, there is no delay within any of these apps. This only happens with the new Netgear C6300 modem/router and my Note 3. The other strange thing is that once this delay has passed, I have no issue with download speeds or any buffering during playback. It all just seems to be that initial connection. I even went as far as doing a hard reset on my Note 3 no see if that solved the issue, but nope. I am currently running Android 5.0 and the Netgear 6300 is running firmware V2.01.19. Has anyone else experienced this? Have any ideas as far as solutions? Help is much appreciated.
Just got the new shield tv box and my wifi speeds are incredibly slow. Get 100 mbps on all my other devices, but 5 mbps.
Anyone know of a solution?
i have exactly the same problem on 2.4ghz wifi. i even put the router right next to the shield tv. still only 6-10mbit (max. 15mbit) while i have a 100mbit connection from my provider. on the 5ghz wifi i get about 60mbits but on both i have huuuuuuuuge packet loss every 3-7s. makes gamestream impossible :/
i even bought a new router. tried with my standard fritzbox 7390 and now with a new linksys wrt1200ac. results are the same slow and bad connections to shield. everything else (i.e. notebook, smartphone, pc) works just fine...
Unplug any peripherals connected via usb and try again. This means wireless mouse, usb hub, etc.
I've found the only way to get consistent speeds with the shields wifi is to use a usb hub that has it's own power source.
Can confirm. Having an extremely hard time streaming anything in 4K on Netflix. 350 mbps Download and 30 mbps Upload. Netflix network speed test shows like 29 mbps... I installed a browser and went to Fast.com and get about 80 mbps. Downloaded the "Fast" app on my Pixel XL and immediately got 250 mbps down standing in the same room connected to the same 5 GHz Wireless-AC network. Amazon Prime eventually decides to stream in UHD and HDR, but it takes a while. Youtube, oddly enough, streams in 4K almost immediately.
Router is an ASUS RT-AC1900P.
I'm still having issues. Has anyone solved this problem?
There was an update recently and the performance in Plex seemed to get a little better, but high quality videos still stop and buffer.
Are there any debug tools on the shield that could be used?
Ok so I had terrible performance on 2.4ghz. on 5 GHz it only connected once so decided to have a look at my modem settings and tweaked it.
Have it set to
802.11a/n/ac mixed
Channel auto channel 112
20/40/80 MHz
Everything working smoothly now with no dropouts
I'm having the exact same issue with my new 2017 Shield. If I restart the Shield, it will occasionally work at full speed on 2.4 OR 5 Ghz. But most of the time, it's under 10 mbps - transferring from the internet OR from my PC that is hardwired to my router. I already had an RMA done, and I'm having the same issue with the new Shield NVIDIA sent me. I've tried every channel possible, used tools to find the proper channel, etc. Same slow speed. None of my other devices have the same issue, even in the same location. Nothing is attached via USB.
What's the deal? Any solutions?
Having problems as well. I have my wirless router I'm a good distance running 350mbs and I can pass the test for the games. When I try to play the games they instantly show I'm having wifi problems.
What are some particulars why my G3 is suddenly getting intermittent wifi at a certain range when it's been in the same room for years and never had an issue? It was working fine before and now it cannot sustain wifi connection despite "showing" an initial max/good signal, especially when it starts initiating such as loading a video on YouTube. However, it works fine when in close range to the router which makes it confusing if it's the WiFi antenna hardware already or some sort of new interference.
tl;dr
1. Works fine when near the router. No connection loses. WiFi signal in my room is good/excellent regardless.
2. WiFi SSIDs show up, then remains SAVED, the says no internet, then randomly connects and works.
3. Connection drops the moment I open a YouTube video, load an app, etc. basically when there is loading involved.
4. Phone has been in my room for years so the range is good and consistent.
5. Other devices can see the WiFi connection just fine, it is just this phone recently that showed a problem suddenly. WiFi signal at good/excellent for every other device.
6. There are other WiFi SSIDs of neighbors but only around 3 or so and they've existed for a while already. We are also in the appropriate channel away from theirs via WiFi Analyzer.
7. The router signal strength is able to reach even up to the house beside ours in the garden.
What I tried:
1. Reset network settings via Backup and Restore.
2. Changed ROM.
3. Removed Blokada / VPN. Private VPN is off.
4. Turned on Airplane mode, then turned on WiFi.
5. Channel WiFi channel, router Mhz, connected to 5 Ghz.
6. Removed Bluetooth devices in the area, Bluetooth toggle at off.
7. Went near the router to connect, it's sustained, then walked over to the room, connection drops. Other devices sustain it.
I understand the phone is showing its years but curious what could be possible reasons for this new issue to appear.
