Getting fluctuation in WiFi Speed in Mobile Devices - Android General

I use a tplink wr 841 hp router, connection speed is 5/6 Mbps. in the full coverage area of the router, if I download on PC, i easily get 5/6 Mbps, but in mobile speed is wildly fluctuating, like 0-2-4-5-3-1-5 Mbps.
I use a Galaxy S7 , My brother uses HTC desire 820 (snapdragon 615). I found speed fluctuation on both of the devices,
There is not so much wifi's in my place, I get 3-4 other wifi while searching, then How can i improve my speed ?

Bad wifi signal?

Hey guys, just did some Wifi testing on my phone, getting some really bad results. Wondering if you guys are getting similar results as I am. I'm using speedtest site on my home computer and speedtest app for my phone. Both the computer and phone are sitting next to the router, no more than 1 foot away.
Just to note, I use Verizon FIOS as my home connection.
Computer results are almost identical after numerous tries, numbers don't differ.
29-31 Mbps down
23-25 Mbps up
Ping: 9-11ms
Now the phone through wifi at the same distance.
11.74 Mbps down
4.2 Mbps up
ping: 58ms
15.81 Mbps down
1.9 Mbps up
ping: 63
11.72 Mbps down
1.64 Mbps up
ping: 175
8.27 mbps down
1.63 mbps up
ping: 166
13.41 mbps down
0.75 mbps up
ping 80
and it just keeps going inconsistent at that rate, the upload especially, never seems to be able to get past 5 mbps on Wifi.
4g speed is fine though at about 12 mbps down and 5 mbps up at 50-80 ping.
I still have my Droid INC so i'm testing the wifi on that as well, getting a lot better speed at about 20 mpbs down, 12 up.
Anyone experiencing similar results or is my charge just defective.
My wifi is terrible on this device. I will have full wifi service in my livingroom with all of my devices (I use an airport extreme wireless router) and cant even get wifi at the same spot with my charge...its pretty disappointing. Other devices include my thunderbolt, incredible, iphone, xoom, ipad, and ipod touch...not to mention my laptop...idk if its the EE4 radio or what the hell would cause this. I've tried different kernels with no luck at all...
I've noticed the WiFi signal is weak when I first unlock the phone, but then after a minute of use, it gains strength. Maybe its a battery saver thing?

Slow Wifi on 2.4GHz and 5GHz

Hi guys,
Never really noticed before, but running tests on both Wifi bands on both my nexus 5 and nexus 7 reveals the nexus 5 to be almost a third slower than the nexus 7!
Consistent d/l speed on nexus 5: 10-16mbps
Consistent d/l speed on nexus 7: 45-55mbps
I have fibre optic broadband at around 65mbps.
I even get higher on 4G (UK) reaching around 30mbps.
I've tried both bands at home and both yield the same, slower speeds on my nexus 5.
Anyone have any ideas as to why this might be?
Thanks,
Td
I achieved higher speeds when I set the control channels in my router's settings to the lowest channels possible.
Try upgrading the firmware in your wireless access point.

Nvidia Shield Tablet WiFi signal

My WiFi signal seems really slow and weak I have a pretty fast WiFi connection on all my other devices is there anything I van do?
What is the signal strength?
Ideally you would want all of your bars, but 3 should be good enough.
How many devices are using the internet at the same time?
What signal is the router broadcasting?
In have had no problems, except in my bathroom, were the signal goes down to one bar and "slows" down the connection.

I noticed that when your hand is over the left hand corner it will make the signal drop a bar or two and when you take it off it goes back up..weird
After upgrading to Android 5.01 via OTA, my upload speed for 802.11a 5Ghz band improved quite a bit giving me 50 meg down, but when switching to use the 2.5 GHz band on my router, speed drops to ~3.5 meg down. I checked speed on my Nexus 4 using the 2.5 GHz band and got around 35 meg down. Something is not quite right with the Shield WiFi when it uses a WiFi network using 2.5 GHz band.

That's why Nvidia says to specifically use the 5Ghz channel, not the 2.4Ghz.
I haven't received anything specifically from Nvidia stating not to use 2.5 GHz channel. Not everyone has a dual channel wireless router, so to upgrade just for the shield maybe not in the cards for some. There has to be a better answer than 'use 5 GHz only'. Most public access points aren't 5 Ghz channel.

WiFi strength, range, and throughput

Rate this thread to express how you think the Huawei Nexus 6P's Wifi performs. A higher rating indicates that it has excellent range, throughput, and signal strength. Like when you're taking a dump in the bedroom upstairs, do your videos have to buffer or do they come through without interruption?
Then, drop a comment if you have anything to add!
WiFi strength is good...nothing spectacular.
Good wifi.
Works pretty good. Pick it up outside in my car from my parking spot. Not strong but still connected.

Wifi is great here....... @svetius how are you doing Sir.........long time
I don't know if it's my router (I just bought it 2 days before my phone came in) but my download speed is not very good. I have a 50mbps down and 25mbps up, but when I run speedtest I get anywhere from 1-30 down and always 25-30 up (normal). My upload is always fantastic, but down varies greatly. I don't know if it's the router or if it's my phone. In all situations I am less than 10 feet from my router.
Can anyone run speed test on 2.4ghz and 5ghz bands and inform me if they see odd download speeds? By odd I mean jumping up and down a lot.

Couldn't agree less, the wifi reception on this phone is worlds better than my 2014 Moto X, I'm getting 2-3x the bandwidth at the furthest distances in our house.
Substantially better range and throughput than my N6.
Find my wifi is good. No better or worse than all my other devices. Picks up where i expect it to and loose it where i expect it to. Again speed is on par with my other devices
Wifi on 6p is much better - get full 118Mbps download (cable limit) with Nexus 5 typically doing 80Mbps download at same time frame. Connected to router at 585Mbps but I have seen it a 7xxMbps rate to router but effective internet still cable limited.

I also am getting faster WiFi performance by a good amount WHEN I do .. reason saying that is that the results are very variable. I would like to attach a screen print I saved but do not see how.
Great throughout with alright range, wifi drops at less range than my Note 3 and S4. This based off two N6P, first device I returned as the auto rotation was broke.

My WiFi has been significantly better than my s4 so far with better throughput, latency, stability. My home connection is consistently above 500 Mbps.
First image 5ghz, Comcast 105-150mbps depending on time of day. Second image is 2.4ghz
WiFi is infinitely better than my previous phones, and 5ghz AC works better than on the iPhone 6s plus in the same spots. Signal strength on 5ghz AC is always 5-10db weaker than 2.4ghz. Plus, I get my full 90mbps everywhere in my house with 5ghz. 2.4 caps around 50-70 because of no free channels. Huawei did something right with the antennae, because I have no issues ever with signal/speed.
I'm getting lower pings and faster throughput on my 6P than my iMac 5K!
Of course, the position of my iMac may make a difference - but, regardless, that's bloody impressive. Huawei has always been pretty good with antenna design, and the larger size of the 6P presumably also helps?
In a test just now I got 9ms, 7.6 Mbps down, 1.1 Mbps up on my 6P (connection 526Mbps) and on my iMac 19ms, 6.8, 0.8 (connection 527Mbps*).
(* bit odd that one is 526 and the other 527 - maybe a rounding issue as I assume they're fixed increments?)
I'll second that WiFi speeds are noticeably faster than they were on my N6.
I haven't done any actual testing, but the primary thing I've noticed is that transfers to my local server are typically 20-30% faster.

On 5Ghz I got 72.2Mb down and 19.6Mb up on a 72/20 connection, so its running it flat out. This was through the speedtest.net app.
The signal on my 6p is significantly better than my Oneplus one. I tested both where wifi signal is lowest and tested both 2.4 and 5ghz bands. Pings are almost identical.
6p
5 ghz - 64.81 down / 12.19 up
2.4 ghz - 57.91 down /12.25 up
1+1
5 ghz - 30.70 down / 12.22 up
2.4 ghz - 17.30 / 12.16 up
Constantly drops Wifi. Then often forgets networks and even can't see any while scanning.

WiFi performance in recent patch

My house has 50/20 Mbps internet. I'm using dual band WiFi, 5GHz on one router and 2.4GHz on another access point, both sit at the same location.
Previously I've been using 2.4GHz when I'm on 2nd floor with no problem gets about 30 Mbps when doing speed test, which is acceptable by me.
I'm not sure when but maybe within this few months, speed when I'm using on 2nd floor drops to 5 Mbps or sometimes even low as 0.3 Mbps. My iphone 4S still gets 20-30 Mbps.
Signal strength is the same as before about -70 to -80 dBm
It has no problem when I'm in line of sight from the access point.
Has anyone been experiencing this? And any solution
Thank you
PS. I still haven't reset the whole phone yet, but I have tried resetting network settings
