Hey guys. Hope you guys can help me out here. We have Wifi at our college and I use Redmi note 3g and my friend who sits right next to me has redmi note 4g. My friend who has note 4g has higher download speed than me in everything(play store, torrents, browser downloads, etc) while mine is very slow. When downloading apps in play store he gets around 2mbps while I get around 30kbps. Another guy who sits two benches in front of me who uses note 4g gets the same speed as my friend. When I checked their wifi options they had an option in advance settings where they can change their wifi band while my phone doesn't have that feature. Other phone users get same speed as me. The guy who sits in the bench ahead me uses iPhone 5s and he has download speeds same as me(around 30kbps). So why do note 4g users have high download speeds than note 3g? Is there a way by which I can get the same download speed as they do?. The wifi router is around 10m away from me. Me and my friend use the latest miui 7 versions.
bro wifi limited speed happened often after flashing a new rom and somtime no happened , but if it happened whats the solution?
i do this :
1.wipe dalvik cache
2.pull out ur battery and turn off the modem for 30 min
3.cut off the lan wire from modem
4.turn on ur phone
5.turn on the modem(ur phone should connected,no more device,just ur phone)
6.it will be ok
Mine Xiaomi mi note 2 never reaches more than ~ 45 Mbit on Wifi (tested with speedtest.net app). Someone also have this problem?
Rom - official Chinese 8.0.15.0, no root, no unlocked bootloader.
No issue here.

(Use "request desktop site" with http://beta.speedtest.net to avoid having to download the app)
There's only a 1x1 antenna in the Mi Note 2 so using a 2.4GHz network without channel bonding will max out somewhere around 50Mb/s in practical use. Oddly about half the time it will only use 20Mhz rather than the 40Mhz it's capable of though I think this is ROM dependent and I can't think now which roms offered channel bonding. It seems pretty clear that 8.0.15.0 doesn't though.
Upgrading to a 5Ghz network will help a lot, you could also upgrade to the latest rom and see if that improves things.
Hello. Just want to say that everything started after “some kind of update after 8.0”.
I tried all the official firmware, modems, etc. Nothing helped.
My problem:
1. Very long ping 4g / 3g (speed test by okla)
2. Even longer ping when uploading data with a very low speed (0.01mb)
3. During a conversation, my speech is interrupted, but I hear the other person perfectly
I put IPhone 7 near and got 40mb/30mb speed....
tested several sim-cards - same result.
I took "network cell info" from gplay and find that at -80dbm I loose Internet connection but iPhone 7 and Xiaomi RN2 with same network quality got 4g
Same result. And after the November firmware (that was not so fast but at least it worked) I only got even worst signal.
I am using 3 yr old redmi note 3, I am facing a problem of network connection frequently. Whenever I play online game I lag badly, in morning time my ping is 250 something but in evening and night it becomes 600 plus. And also my network become stale and I have to switch to airplane mode and then back and then it works fine till I leave it idle for sometime and it again become dead. I don't face any problems while downloading movies on my amazon prime video and it gets downloaded at speed of 4 to 5 Mbps. Then what is the problem. Is it network issue or my mobile handset issue.

The easiest way to understand this is to try another device.
You can also ask people who use the same network and tariff. If they don't have a problem, it's obvious that the problem is your phone
Hi all, just picked up a Tab S5E today - love the screen, built quality etc. What I don't love is the Wi-Fi performance. I'm left very confused.
I installed Android 10 right out the box and did a clean reset - after which my link speed in Wi-Fi settings shows 86 mbps throughput. For reference, my other phones (Oneplus 5 - 3 years old and Oneplus 8 Pro both show 866mbps receive and transmit speed).
When right next to the router I get a max of about 150mbps, with an average of 80mbps on Speed Tests - This is the case whether holding the tablet or not. When about 5 metres away through a wall this goes down to 45-55 Average, in comparison both phones show around 280-330 average.
When right next to the router with my other phones I get my networks full download which is 550mbps.
I understood before purchasing that if holding the tablet in the bottom left corner when in horizontal position (camera on the left) you are likely to lose signal - potentially mitigated with using a case. However, by wrapping my hands round the left antenna, on average - the speed increases to around 150-170 - odd...
When attempting to put pressure on the antennas from both ends and firmly wrapping my hands around the tablet, I do not see any network connectivity issues relating to dropouts and the WiFi bars remain on 5.
Honestly not got a clue what's happening here, either who have decently fast connections don't big this up online, or this is just a weird hardware fault with my unit.
Pretty disappointed. If anyone has any advice / screenshots of their speed results higher than this - I would greatly appreciate this, in which case I will definitely pursue a replacement device. I can't accept that in 2020 a device cannot achieve full 5.8ghz WiFi speeds when directly next to the router.
There is nothing wrong with your device. The maximum WiFi speed on the Galaxy Tab S5e is around 160 to 180 Mbit/s. I didn't expect this either when I bought this model and it is also a major bummer for me.
The device supports 802.11ac, but unfortunately Samsung only put a single antenna into it which limits it to a single MIMO stream (on a 80 MHz channel that gives you theoretical 433 Mbit/s throughput, which of course no device will ever reach). I would expect something around 220 Mbit/s with this configuration, but somehow the maximum speed I get with this device is only around 160 to 180 Mbit/s. It is not only the speed that is bad, it is also the signal strength that is exceptionally bad compared to all my other devices.
Your phones and other devices probably have two antennas and support 802.11ac with 2x2 MIMO which gives you theoretical throughput of 866 Mbit/s and around 500 Mbit/s in practice.
Thank you for your reply. I just received a replacement unit and tested before updating to the Android 10 update. There was indeed something wrong with that previous device as the link speed shows 433mbps and I consistently got 280-295mbps download.
However, I just updated it to Android 10 - now it's completely gone again. Link speed 87mbps and downloads of 20-70mbps. This is most definitely a software issue which I'll be contacting Samsung about.

I also got a WiFi issue when upgrading to Android 10. My tablet was working perfectly before the update but now will not auto connect. I agree this must be a software issue.
I have just upgraded my tablet to Android 10 and the Wi-Fi speed maxes out at 60 Mbit/s. I'm thinking about selling my device again, this is unusable.

All I can suggest is to create a bug report in Samsung members app. I did so over 10 days ago now and am awaiting a response. The more people that do so the better - a fix needs to be rolled out for this. Something's quite wrong with how the WiFi module is working after this update, probably driver related.
Has anybody tried wiping the cache partition in Recovery Mode? If that doesn't help back up your device and perform a Hard Factory Reset. That normally fixes any software issues.

With both the tab s5e's I've had I had reset them both twice, and cleared cache in recovery.
This is definitely an issue brought about with the update considering Android 9 was absolutely fine network wise.

In that case you may have purchased a unit from a bad batch.

I disagree, this is definitely a new problem that was introduced with the recent Android 10 upgrade. Samsung made the Wi-Fi signal "more stable" by limiting the modulation type to QPSK (MCS-2) instead of 256-QAM (MCS-9) which effectively caps it to 87,8 Mbit/s on a 80 MHz channel. Instead of 180 Mbit/s with Android 9 (which was pretty bad), users are now getting around 50 Mbit/s (which is incredibly bad).

My S5e won't auto-reconnect following the recent upgrade to Android 10. Also stutters and freezes for a while after restarting in various apps and settings. System software issues presumably.

Thanks for doing the research to find this out. This definitely explains exactly what I'm seeing.
Very disappointing as I was achieving fine speeds 290mbps or slightly higher prior to the update. Now WiFi on the whole is pretty poor in comparison.
Why was this done intentionally - it really makes no sense. Surely this must get reverted.
I just got an update this morning aimed at WiFi improvements

I can confirm this update has fixed all issues for me. Normal 433 link speed when next to the router and the same WiFi download speed as on Android 9.
Since updating to Android 10, I started having issues with mesh wifi (I'm using Google Wifi). Same position and setup that used to work perfectly with Android 9, now the table starts disconnecting from Wifi and I have to reboot to reconnect. Anyone else has this issue?
I'm contemplating buying an S5e tablet (in Australia). Does the reduced speed of WiFi impact on any practical applications ? My internet cable subscription is for 50mbps. It used to be 100mbps, but I dowgraded on purpose, seeing no benefit for the cost. Even at 50mbps (practically 46) we have moments like today when both myself and my son are working remotely to different employers, while my wife us watching a video. I realise there could be apps which require more bandwidth, so I'm just curious what those might be.

That is exactly my problem as well. Google WiFi and random disconnects from the tablet that sometimes get fixed by disconnecting/reconnecting but majority of the time a restart is the way to solve it.
No other device in the household gets disconnected from the network (neither was the tablet before upgrading) so it is definitely the update to blame.
Having similar issues following the update. I tend to turn the tablet off when I'm not using it, and thus far I have yet to successfully connect to WiFi on startup. I have to manually toggle WiFi to get it back on.
Same wifi issue here after updating to Android 10. Is there a way to manually update using file some were receiving in late July?
I am really bothered by this GROSS limitation too! It makes issues with the driver even worse.
Maybe our answer can be found on this page or something or nothing ?
