Hi there,
I've a Infuse with Zeus 6. The 3G Internet speed on phone: web browsing, map, google play,... is pretty slow. But if I using Hotspot feature and connect from my laptop, speed is great. Did I mess something on phone configure?
TIA,
giobuon.
Hi, I have a Xoom Wifi, originally Canadian but flashed the US firmware, and updated to ICS 4.0.4.
I've noticed that the Wifi tends to disconnect sporadically and only while streaming video (watching YouTube videos, either in the YouTube app or on Chrome, or streaming from a local machine via Plex or Emit). It never ever seems to happen when doing normal browsing, or even copying large files via a shared network folder, only when watching video. Rebooting the tablet seems to fix the problem for a while, but wifi starts dropping about 20 minutes after booting and loading a streaming movie.
I've tried changing DHCP to a static IP, changing the wifi channel, and several different routers, and the problem stays the same. Has anyone else experienced this or heard of a fix?
Hi All,
Have lots of stutter playing a video over my local WIFI. Video is 6Mbps (720p). When copied to external SD card and played from there, it's smooth. So I'm pretty sure this indicates my hardware and MX Player is all fine. I'm using the KitKatt 4.4.4. ROM.
Things change though when I play this through BubbleUPNP (source is minidlna on FreeBSD). No transcoding should take place. Then I get lots of stutters. Have also tried to play this by using File Manager HD, connect with sftp and open the video directly. Probably plays slightly worse.
Does not seem to be a CPU issue, I watched this with top, load tends to stay around 0.7, sometimes getting up above 1, but can't find much relation to stutter. CPU is around 23-40%, with 60% idle.
You would say this indicates a network performance issue. Have the tablet is within a few metres of the Netgear R6300 route I have, and distance doesn't seem to matter too much. When using a tool like Speedtest.net I hit 17Mbps over my ADSL network, so WIFI doesn't seem a limiting factor. I've even tried iperf, I get 19-33Mbps when doing that (so from tablet to my minidlna server).
I tried copying the file with File Manager HD to my external SD card, but felt slow, i.e. perhaps even less then 1MB/s. But that could be File Manager HD or the write speed to my SD card, not sure.
Other things I've tried: different player, doesn't make any difference.
I'm grateful for any suggestions people may have. Playing a 720p video over a DLNA network shouldn't be this much trouble.
Some more observations: on an old laptop, link speed 54Mb/s, I have an iperf value of 34.6Mbits/s. If I do an rsync of a 1GB file I get 2.88MB/s, so quite respectable values.
Have installed "WiFi Speed Test" on my TF300T and get 21.91Mbit/s with the tcp client test (download), which is quite respectable, and perfectly in line with other tests (AnandTech for example). However, when I do the smb client test, I get between 5Mb/s to 6.5MB/s.
Using rsync, if I download the same large file as with the laptop using rsync, I get about 1.67MB/s.
So clearly I have an issue with this tablet or ROM, not with my wifi network it seems.
Keen to hear "WiFi Speed Test" values from anynone, especially SMB/FTP values. The problem doesn't appear to be with simplistic tests (iperf), but any more complex network protocol is a lot slower. But having said that, 1.6MB/s should be enough to play 6Mbps video, but possibly the rate may not be sustained enough. Continuing the investigation.
If on your link you only get 5Mb/s to 6.5MB/s. on the smb test , it's kinda expected that your 720P / 6Mbs video will stutter, especially if it's variable bitrate or when the network fluctuate.
smb protocol has a lot of ovverhead and tends to behave badly on wifi / latency so you get less throughoutput on smb than rsync or a direct tcp test
If you don't need transcoding, you will be better to mount the smb share natively (use something like cifs manager for example) and play it directly from there.
Playing a video through the file manager's sftp or smb own libs is less efficient and will tend to give stutters every now and then as its process goes in background while the video is played in foreground.
As for stats: on a 65 Mb/s wifi link I get the following on my TF300T:
tcp client: 43.6 Mb/s
rsync: ~17Mb/s
native smb: ~12Mb/s
wifi speed test smb: ~8Mb/s
file HD manager smb: ~5Mb/s

Yeah, that's twice of what I get, so all your numbers are double of mine. Maybe it's my Netgear router?? I'll test against a different WiFi router.
On a Samsung Galaxy Note 3 I get 26 Mbps - 47 Mbps. Considerable fluctuation.
I have now tested the tablet against another R6300, no nearby wifi, performance worse then I have at home, and at a company wifi network, also not so good.
I then replaced the firmware with the latest DD-WRT, nothing much seemed to change.
I have no wireless security enabled on my network as all clients use openvpn. I then switched to using WPA2+AES, and turned off openvpn. Suddenly I started to see numbers much more similar to Tim's.
Obviously I had tested with and without openvpn against stock firmware, but that didn't seem to make much of a difference. And the fluctuation was always considerable. But with DD-WRT it seems to make quite a difference. Hit 40Mbs with wifi speed test tcp client pretty regularly.
However, it didn't make any difference with playing the video! But thanks to DD-WRT I now have graphs for bandwidth monitoring. What I saw was spikes of 40-60 Mbps for several seconds, then nothing for several seconds, then it spiked again. What it seems to me is that the MX Player, or more likely BubbleUPnP client, has problems prefetching the content. It simply doesn't do it consistently enough at 6Mbps, causing stuttering, because when the buffer is empty, it can't fill it fast enough for a second or two.
Bandwidth test for wifi shows over 100Mbps
Bandwidth test for 4g LTE shows over 35Mbps
When clicking a link, wifi connection lags out for 10 seconds before loading
When clicking a link, 4g LTE connects immediately
Why does the wifi connection lag out for 10 seconds after clicking a link despite the fact that the DL speed for wifi is almost 3x 4g LTE???????????????????????
Any ideas?
Apparently it has to do with google's DNS servers and Lollipop. Installing the DNSet app fixes the issue.
Anyone tried Moonlight game streaming (aka NVIDIA GameStream) on their U11?
Long story short, the U11 seems to have issues streaming over WiFi where other lesser Android phones do not.
1) No matter what the bitrate, I get constant stuttering and the audio is very choppy on the U11.
2) My AC1900 network pushes well over 200Mbps with 3ms latency on speed tests on the phone.
2) It DOES work perfectly with a USB ethernet adapter. I can set set Moonlight to 1080p 60fps @ 40Mbps and it streams fine - no audio issues, no frame drops.
3) My Surface 4 (Moonlight Chrome plugin) and Nexus 5X (!) (same Moonlight Android app), can stream nearly perfectly at at least 20Mbps on the same network.
4) Even a crappy Moto E streams pretty smoothly @ 10Mbps on 2.4Ghz!.
So to me this clearly seems like a WiFi latency issue specifically with the U11....
I've tried:
1) Both 2.4Ghz and 5Ghz bands, same result.
2) 2 different AC1900 routers, same result.
3) Enabled "High performance mode" in developer options, same result.
What I'm wondering is, what happened to the "WiFi optimization" setting on the phone - did that get removed in the Oreo update?
Has anyone encountered something similar - wondering if maybe someone on a non-stock ROM/kernel has any different experiences?
I'm mostly just pissed that it works perfectly fine on other Android phones, but not the U11.
EDIT: Factory reset the phone and it resolved the issue.
Try an app called boost+ by htc. You might ha e too many programs battling for ram.
Try checking your Internet settings. Most carriers won't let you change this but a speed testing app might help find the bottleneck.
Try an app called adguard. Lots and lots of adservers run in the background without you knowing. Even when offline they still keep pinging and retrying until they get a connection. Adguard will blackhole them.
High performance mode shouldn't be necessary as when off battery saver it runs at full tilt anyway. When you play on data plan deactivate wifi completely. That will stop the phone constantly pinging wifi.
