WiFi speed - Samsung Galaxy A51 Questions & Answers

When I check the WiFi speed on my phone at home it can be low. If I turn the WiFi off on the phone and back on, the speed increases dramatically.
Is this normal or is there an issue with my Samsung A51 phone?
Thanks

Are you sure it's your phone? Have you tried using it on a different WiFi network?
If you have a "mesh" network in your home it's possible that the phone is connecting to an AP that's further away at first, and is unable to maintain high throughput until you toggle WiFi, then it'll reconnect to the nearest one.

Your device will connect to 2.4GHz, which leads to lower speed, when you are 5 or more meters away from your router. After turning off and on your device will compare 2.4GHz and 5GHz and will choose on of them and stay connected to them until you turn off and on your WiFi again or 5GHz lost connection. Long story short; Yes it is normal

I omitted the following from my initial post
At home I use a Three 5g hub which gives me almost 300mbps on the phone.
The drop I mention can be down to 50mbps
Other equipment in the house isn't effected.
I'm typing this and thinking eureka, it's the phone!
Thank you for your help guys

Wifi SLower than should be..

I have a linksys wifi N router at home and my laptop connects at around 144mbps, however my phone only connects at around 72mbps..
Also my laptop always sits on my coffee table which is about 15' from my router (through one wall) and has excellent signal. But my phone usually only has good signal in the same spot. It only usually lights up like two of the wifi indicators.
Does everyone else have this issue? Are the wifi chips just not strong in the phone or what?
My laptop is currently saying that it is recieving at 54mbps, my mesmerize is showing the same speed. Although my laptop is stating that I have excellent strength, and my phone is showing fair strength. I think the wifi is only so-so in this phone, I rooted last night and just got wifi tethering going. With the phone broadcasting a hostspot next to the laptop it only gave a fair signal strength. I'm not sure if the strength of a wifi hotspot has anything to do with the recieving end of the signal though.

I've had this issue with both my droid and my blackberry (when I used my blackberry). I think that the wifi capabilities in phones are not as good as they are in computers.
but the reason I'm asking this is this phone is supposed to have wifi N radio in it.. Older phones only had G antennas which are only capable of 54mbps.. wifi N is theoretically capable of up to 300mbps, I've never seen anything actually connect at that speed, but it would seem that my phone which is brand new should atleast connect at the same speed as a 2 year old wifi N laptop???

If your router is only G that's the max speed you will get?
Wifi is a pain in general to troubleshoot, as there could be many, many reasons why it is slow or not working at all.
General questions to be asked are:
Do you have security enabled wifi?
What kind of encryption are you using?
How many devices are connected to the network? (Wired or wireless)
Is the router set to send a wireless N signal? (most routers have that optioned, but not always running as most devices are not wireless N compatible)
I've had my phone connected at several wifi's (I travel a lot for work and am in hotels all the time) and my connection speed varies. At home I have great connection and speed test to 5megs a second download (wireless N--it connects) currently at a hotel in Colorado, 1480kbps download (wireless G)
I still stick by my thoughts as far as the wifi on the phones will never be as good as the wifi in a computer, be it a laptop or a desktop. Phones just don't have the battery power to hold a super strong/fast wifi signal.
I have wifi speed problems also but my first gen ipod touch does not seem to have issues

yes, the router is set to wifi N or actually it's set to all!!! I have security enabled..
There's only two devices running wifi (laptop/cell phone)
I get fast download speeds like 5000kbps down/2500kbps up when using the speedtest.net app..
But when I go to wifi settings and click on my router once it's connected whether I have Good (usually) or excellent it's only connected to my router at 72Mbps.. I have a static IP set for it..
I guess mobile phone wifi chips just aren't up to par with laptop chips

Those are my sentiments exactly. Even with it not being as fast, it's plenty fast for everything I need it to do, but 3g is fast enough for me generally. I only connect to wireless when I'm not in good cell service.

Wifi Issues

When I move into my room, my laptop gets 90%-100% signal strength from my Wifi, my phone however randomly looses signal completely and especially when I take up the phone to use it. It's very frustrating. Plus when I'm on 3G, it constantly switches from 3G to H too.
The 3g H switching is normal if you are on tmo us and running the eu roms and has been discussed quite a bit
not sure what you mean by losing signal, but i get diff bars diff places in my house. never lose the whole connection as in not being able to dl or browse web
did you run speed tests at these diff locations in house

I think you misunderstood his post. His primary problem is that the wifi on his phone doesn't come close to the signal strength his laptop has when in the same room.
The secondary problem was the 3g/4g switching.
OP -- I have no idea what to tell you.
no, i understood. just saying my phone wifi bars fluctuate even if my laptop has good signal. may just be the way they both display strength readings
i think op should run speed tests btw the two at same time. however both devices are splitting signal so may not be as good as only one running at a time
his speeds may be fine even though bars don't show it

I'm in Jamaica, no T-mobile. I'm not sure if I'm running an EU rom. My problem is that I loose connectivity to Wifi totally randomly in my room with even little motion. I mentioned my laptop for reference... it's like there's poor signal in my room. The phone'll just bit sitting on my bed, I hear an alert and pick up the phone to realize I've lost Wifi.
Speed is not the problem, I've been able to run a speed test to confirm I get the speed I'm supposed to get. Other times though, the speed test could not complete because I moved a little and lost connectivity.

Make sure that your SIM access cover is snapped in place.
It happened to me with the WiFi signal - The phone was losing signal, and had low signal 1 foot away from the router.
I 'pinched' the top-right corner of the access cover (thumb on the glass, index finger on the back cover) - I heard a 'click' and suddenly my WiFi was at full strength. I believe that the WiFi antenna is not connected unless it snaps together.
ok, not sure what to suggest. you could try turning airplane mode on and of and see if that helps
maybe router settings with the phone if you always had the issue
under settings/wifi/ tap on wifi then the 3 dot menu--Advanced. See if Keep Wi-Fi on during Sleep is Always. If not tap on it and change to Always
Also at bottom of Advanced menu is a DLNA setting, you could toggle that
barring that or someone else's ideas--maybe hardware and needs replaced
Try turning on Best Wifi Performance in Wifi, advanced settings.

Turning on best WiFi performance totally killed my battery life, but that may just be me.
If you're losing signal on one device but not another, I'd recommend changing the channel on your router. Interference on certain channels can cause weird issues with some devices. There are apps on the market that will show you which channels are congested in your area.

Hmmm... I'll try that. So far turning on DLNA and Best Performance hasn't made any difference. I'll try changing the channel when I get home later and post the results. I REALLY hope h/w is not the problem.. it's gonna be a hassle sending this back.
It might be worth gently cleaning the contacts exposed when you remove the SIM access panel. As District noted, good contact is necessary for wifi (and probably other features). Dust or a fingerprint may be problematic.
Anything to bear in mind when trying to clean it or adjust it? I'm really paranoid I'll mess it up.
make sure you use electrical cleaner
radio shack sells it, comes in spray can
if you haven't had sim card out or phone long, probably not issue. but, worth try
if you have another router, you can always try that
Nothing seems to work... I'm using channel 11 @ home which doesn't seem to be crowded. I have the same issue @ work with our router. I've been having this problem from I got the phone last week. This is after I initially removed the back cover to first insert my SIM.
I'm going to try and see if I can secure a cleaner... I tried blowing on it mean time. Also turned on DLNA and best wifi performance and all.
DLNA auto-IP setting worked for me.
Hi OP,
I had the exact same wifi issues on my One S. I tried the router at work, the router at home and my mates router with the same results.
Mine seems to work now, with no disconnections or manually connections. What seems to have worked for me -- Wifi - Advanced menu -- DLNA auto-IP setting - toggle on. Then restart, making sure the setting is still set after reboot. Seems to have fixed my wifi issues.
HTH.

Slow wifi on N5

After being connected to WiFi for a while the wifi speeds drop to less than a quarter of their normal speeds, e.g. at home 6 Mbps drops to 1.4 Mbps. It is the same at work connecting to an enterprise level AP (although speed drop is 30 Mbps to about 5 so less of a problem).
I know it is device related as other devices tested at the same time are at the right speed.
Toggling WiFi off then on again returns everything to normal speed. Anyone else?
It's like it reverts to power saving mode. Didn't have this problem with my 4 or current N7.

I haven't had your issue and I've been speed testing here and there all day.
Have you tried turning off wifi optimization under wifi/options?
I have turned that off now and rebooted. I turned this off the other day without rebooting and there was no difference but will see how this goes.
Thanks.

Made no difference. Got reduced speeds again.

I had similar problems when my friend connected a Blackberry Z10 to my router, constantly dropping out after about half an hour of connection, so try this:
I found that my at the time SGS2, could only connect in 'g' mode, whereas her BB was connecting in 'n'. I believe this was confusing the crappy B.T. router I have, so I changed the settings of the router to only accept 'g' connections. Problem solved for me.
Worth a try anyway. Especially if the other devices connecting to your router are a bit older and only use a 'g' connection.

There are no drops in WiFi, it just slows. All my other devices are N too.

Odd, I don't have this problem. The wifi a runs at full speed even in low signal areas. Maybe it's something to do with the router?

I have this on my home WiFi with both the Nexus 4 and the Nexus 5. Both are connected to 5GHz 802.11n on a dual-band Netgear N600/WNDR3700.
Performing a test just after boot, the speeds reported by Ookla's speed test app are:
Nexus 4: 46Mbps dl / 12Mbps ul
Nexus 5: 82Mbps dl / 12Mbps ul
After some period of time, the results (recalling from memory) change to:
Nexus 4: 2Mbps dl / 11Mbps ul
Nexus 5: 2Mbps dl / 11Mbps ul
If I switch off WiFi and then switch it back on again, each phone will then return to its previous higher speeds.
Never have figured out exactly what triggers the slow-down; my best guess is that it's something to do with the phone going into deep sleep, or perhaps related to power-saving functions on the router.
A Linux-based laptop is connected to the same AP and I don't notice any issue with that. Don't recall the Nexus 7 having any issues either (though that can only connect to the 2.4GHz radio).
I didn't notice this on my N4, but I never checked, and in retrospect I remember having some problems streaming video when you normally would think the connection would be OK. Will give Google a call.
The problem exists on my home router, an access point I also have in the house (different manufacturer) and at work (different again).
Have tried changing to 2.4 GHz only but no luck.
Thanks.

People had EXACTLY the same problem when Nexus 10 just came out.
If interested here is the thread http://forum.xda-developers.com/showthread.php?t=2124485
Basically, google had to release a fix to solve this problem.
I'm noticing slow WiFi as well on my Nexus 5, with Netgear APs at home.
Also the 4G is weird - here in the UK, upload remains strong but download is slower than other phones running the same speedtest from the same location and a fair bit slower.
Will hold off judgement for now though.
Got an ASUS router at work so gonna test that.
It will not see the 5GHZ band on my Netgear WNDR4500 at all though - then again neither will my Nexus 7 2013
(My Nexus 4 does see the 5GHZ band SSID however then again probably due to different WiFi chipset or something)

Yeah been testing 4G on Vodafone today vs an iPhone 5S - getting consistently slower download speeds in the same locations on the same speedtest servers.
Has anyone else tried using the N5 in and around London on a 10mhz 800 band network (so basically Vodafone or O2)
Also is the 5Ghz 20mhz ? I seem to be getting 70mbit download on a 1000mbit connection
5ghz works on an ASUS router but seems to just be completely absent on Netgear routers (sure its a 20/40/Auto/Band setting somewhere)
Having called Google and tried the suggest factory reset, problem persists so will call again and likely try a replacement.

i have the same problem. it also affects LTE. both cut down by a third or so after some unknown amount of time.
I don't have access to LTE, so can't comment there. I will be getting a replacement tomorrow and will report back then if it is fixed.
Also keen to see if the battery is any better in the replacement. Reports seem to vary wildly on these forums and in reviews but my finding is that the battery is no better then the N4 battery in any way.

Have y'all had Android devices in the past? As in, have y'all had Google accounts to which you've backed up your data (e.g. WiFi credentials) that automatically were transferred over to your new device?
I ask this, because I had to do a factory reset and prevented Google from backing up my data and preventing automatic restore (e.g. I unchecked "Back up my data" and "Automatic restore" before I did a factory reset).
There seems to be an issue where the restored WiFi settings don't sit well with the new device, and you have to manually input your WiFi credentials and have the Nexus 5 configure it from anew. It may also help with slow connection speeds and connection issues in general since I found that after I did this, my connection strength increased (qualitatively; I haven't done quantitative analysis) and the range at which it still connects to WiFi has increased.
Here are some links to the issue that I, personally, have run into, but near the end of the second issue tracker, someone has ADB commands that essentially accomplish the same thing (i.e. wiping all stored WiFi data)
https://code.google.com/p/android/issues/detail?id=58230
https://code.google.com/p/android/issues/detail?id=61945
Might be something to try before you send it into RMA (since it will take like, 2-3 weeks to get the replacement phone, and even then it sounds like this is a purely software issue).
EDIT: Note, that unchecking the "Backup data" and "Automatic restore" (I think doing the former will automatically grey out the Automatic restore option anyways) means you will have to reinstall all your applications manually one by one. This is probably easier if you just log onto a computer and have Google Play in a browser to download it to your device.
Furthermore, my specific issue didn't lay with slow WiFi speeds, but rather with the inability for the Nexus 5 to automatically reconnect to a WiFi router once it exited and reentered range. It was also unable to manually connect to the router unless I cycled WiFi or Airplane mode (or reboot the phone).

I always choose not to restore my backed up settings to a new device, and so manually create the WiFi connections. Doesn't appear to make any difference in my case.

I had a similar question, but I just want to know why I see 72 Mb/s connection in the info, instead of 150 or 300? Asus RT-N66U with Merlin firmware, 802.11n only, 40MHz bandwidth (but also tried 20/40MHz). All computers show 150/270/300 (I know these are just theoretical). My wireless desktop can transfer a file at 10MB/s...the N5 (and a 2012 N7, 2013 N7, GNex, and Nexus S) do about 2MB/s.
I'm having exactly the same issues as t2002 and TheFluffyOne - Just after booting I'll get >10mbps dl but after an hour or two if I run the speedtest app again it will have slowed down to <2mbps. It's horribly frustrating, hopefully it's just a software issue and will be patched soon.

WiFi is too slow

What could be the reason for my Nexus 5 having slow WiFi? I put another phone next to it and ran speed tests with speedtest.net The nexus got around 5~7mbps while my other phone got around 28mbps. The WiFi is just too slow. Often times speedtest even fails to find a server and some other times my download speed is 0.01 or something.
I am on Lollipop 5.1.1
Do both phones show the same wifi signal strength? Possible loose wifi wires inside the phone?

Yes, both have the same strength. According to the WiFi Analyzer app, the Nexus's range is ~-50 while the other phone is around ~-60 (Both are on the same network and both phones are side by side), so that means that the Nexus has better strength yet it's extremely slow.
Maybe the phone needs to be factory reset?

[Q] Note 10 Plus - Wifi Issues

So I have a brand new Note Plus that in two locations will connect to wifi, but I am experiencing significant packet loss (30-70%) if I ping from my phone to the router. Both locations use a Cambium E410 Wireless Access Point. I have taken it to 2 other places and experience no wireless issues.. I was trying to see if it was a 2.4 or 5Ghz issue potentially, but I can't see where in this version of android to force the Note to use 5Ghz vs 2.4ghz. Also trying to determine what other troubleshooting I could perform...
I have to problem with Wifi. Realy bad reception and when BT is on it's even worse. ???

Is the router wireless too? Then switch off the access point and try to connect to the router directly and check. For the best speeds, every wireless access point should be connected to the router with an Ethernet cable. Put all the above - both wireless access points and the router - all on the same ssid and password but different channels so they don't step on each other (which might also be the problem). Then, your devices will automatically connect to the one with the strongest signal and not even know or care about it. You will have to set the channels in use rather than leaving the devices on "auto". You can use "WiFi Analyzer" and "WiFi Tool" - both free downloads on the play store. Don't hide the ssid's - unless it is all working flawlessly - later .

Yes you are right, note 9 the range is better than note 10 plus, this is what disappointed me most.
The rest is ok, I had read note 10 only catch the signal is strong, if its weak it doesn't show in WiFi scanning.
Hope they can fix this.
