Hi guys,
I have been trying to watch HD video files from my media server over my wireless network on my Note 10.1. However, no matter what I use it just lags and stutters. The files play when put on an SD card which means it is related to the buffer speed.
Surely it isn't too much to ask for the note 10.1 to be able to stream a film wirelessly stutter free or am I expecting too much?
Thanks
How congested is your network, and what frequency band? Also, which player are you using?
I switched to 5GHz "N" WiFi (as the 2.4GHz band at home and work is just a huge mess) and am using the "Dice" (and "MX") players and I can stream MPEG/H.264 videos with no interruptions.
One thing to consider is if the initial connection is judged to be fast by the player, it might decide to not need to buffer that much, which leads to slowdowns once the WiFi thruput decreases.
It is on the 5Ghz band on my new BT Homehub router. Would I be better buying a separate wireless router and connect it up?
The only other things which use wireless are 2 mobile phones. The computers are wired.
Currently I have shows working okay for 11 minutes and then they slow and stutter. Never to work again! Very frustrating unfortunately.
There IS the possibility your media server might be an issue- I have a couple of PogoPlugs that I use for this purpose, and they work well both over 2.4GHz and 5GHz.

I have the HP MediaSmart Server. It is connected via a wired gigabyte connection.
Unsure of how to solve this issue. Streaming to a laptop over wifi is no problem.

Are you running a stock kernel on your GNote? What's the effective bitrate of your movies? Are there any QoS settings in your router?

Yes mate my note is running stock. As for QoS, I am unsure. Quite sure the router is basic to be honest but given that I can stream to laptops it leads me to believe that my tablet is the problem.

Kinda/sorta- the reason I'd asked about being stock or not is that I suspect the WiFi in stock devices isn't optimized for streaming but more for surfing (there's a slight difference in the way packets are handled between those two modes) and I've got a kernel that uses a different TCP "backoff" setup and I'd wanted you to try that.

Have you check your wifi signal with an app like Wifi Analyzer to see if you have other devices crowding the channel that you are trying to use. You may be amazed at what you find.

He's on 5GHz, though- while not impossible, it's unlikely it's a channel-crowding issue.

You have to start some place and this would be my first step in trouble shooting any WiFi issue.
Also........ The higher the frequency of a wireless signal, the shorter its range. Thus, 2.4 GHz networks cover a substantially larger range than 5 GHz wireless networks. In particular, the higher frequency wireless signals of 5 GHz networks do not penetrate solid objects nearly as well as do 2.4 GHz signals so 5 GHz hardware offers a few advantages over 2.4 GHz hardware, but in practice, 2.4 GHz is usually the better choice for home and other wireless local networks
Higher frequency networks are not necessarily superior to lower frequency ones, its a fact.

Well the lower-penetration disadvantage of 5GHz is offset greatly by the higher possible bandwidth and lower interference rates- but if his 5GHz network is 802.11n, perhaps he's got a mesh setup going on that can help alleviate some of that (the OP's gotta love how we're talking about him like he's not right here, too ).
But I can easily help OP determine if the issue is band-related thruput- can he download one of the movie files? Do that while timing the download, and see what kind of effective bitrate he's getting (I'd also suggest running the Ookla "SpeedTest" app).
I have a UK Galaxy S7 and I am wondering if anyone has had any issues with the bluetooth being perhaps a bit low powered. I have a Bose QC35 bluetooth headset and it works perfectly with my iPhone 6. I recently bought an S7 and the range seems to be awful with it cutting out anything more than a meter away. I have tried different orientations and it starts to stutter with my hand over the top of the phone (I assume the antennas location) specifically with it on my left side. I assume this is because the antenna in the Bose Headset is on the right ear cup. I don't have this issue with the iPhone so it must be a problem with the Galaxy S7. I returned the one I bought as I wondered whether my phone was specifically faulty and the issue is just as apparent on the new one. I have rooted my phone so I cant send it back and just wondered if anyone here had any ideas on what might solve it (can I lower the bitrate of the bluetooth compression some how?).
This video demonstrates how awful the stuttering problem is. The phone is within 1m range at all times and this cut out is obviously not acceptable. Here's a demo if it isn't clear.

Ref the WiFi & cell signal I did notice my previous A5 2016 was reporting slightly stronger signals than my new S7. Tried another & it was the same. Weird.
I remember it was worse when I had a back case on it which I later lost getting into the Gear VR & that not accepting one. Not sure what you could use as a reference point though as the 'bar' system is frequently criticised for it's inaccuracies & there are a lot of signal apps out there to choose from.
Ref the WiFi do you have your router transmitting 5Ghz A/C? Only that's where the best speeds would be to be had with the S7 supporting A/C. Using my TP-Link VR600 transmitting a 5Ghz A/C 80 MHz signal referencing the Network Cell Info app I get about -40dBm with 866 Mbps link speed which gives me access to the full 80/20 offering of my fibre. With Wireless N rather than AC & on a 20Mhz 2.4Mhz channel I would be looking at a Link Speed somewhere in the region of 54Mbps. I wonder if that's where you are?

2.4 Ghz is just a bandwidth, within which there is wireless G/N/AC/{whatever}, all of which operate at different speeds (depending upon walls, and other big tall things that might house steel). So you could get from 50Mbs to 600Mbs depending on those things , but more likely lower.
5 Ghz is just another bandwidth with less range, and less pollution in that range, but still has similarities with N/AC etc and all the usual suspects determining if 5Ghz bandwidth will allow 50Mbs or 600Mbs.
This is just general stuff about bands mostly gleaned from my year of ham radio when I was ~13 or so ; . Where I work, we're using 10 year old 2.4Ghz "real" (not just labeled d-link junk) Cisco wifi access points with multiple VLANs and extremely high throughput. They only handle WIFI g. They probably get double what I get at home (~100Mbs) and are completely reliable. I don't know how much faith to put into some bandwidth except that my own experience is that 5Ghz isn't all that hot for home networks.
The other thing:: Gsam not working right: If you're in emui 4.x and you've somehow managed to enable power profiles, then that's your problem. They work like dervishes that want to kill everything including Gsam & other mgmt services. Doesn't matter what you tell them. They do save power but you will never be able to use gsam to tell.
Disable those things and try gsam again. It's what fixed mine.
If you're in emui 5, then disregard the above since power profiles aren't working there and in fact, aren't in the OS GUI for settings yet. In fact, Until you issue the statement involving permissions (see my other post today about gsam) , it can't even really read anything done by another process. It's a 7.0 feature (yikes!)... ;;0
This seems a good writeup (in answer to a similar question about bands for wifi) that I've looked at before:
It's hard to answer the question "What is the max speed of 5GHz in mbps?" in a general sense. In the context of 802.11 (Wi-Fi), "5GHz" is a radio frequency band -- a range of frequencies that you can use for things like Wi-Fi. A range of frequencies doesn't have a performance limit, other than the theoretical Shannon limit, but calculating the Shannon limit requires knowing the signal-to-noise ratio of the transmission, which varies.
So instead, we have to talk about things like the max speed specified for use in the 5GHz band in the latest 802.11 specs (600mbps), or what the latest equipment can do (450mbps), or what your particular AP can do (300mbps), or what's the best rate a cheap client—such as clients that are only 1x1:1, or don't support wide channels (HT40, 40MHz channels), or can't do Short Guard Intervals—can get when connected to your router (150mbps, 130mbps, and 65mbps are the max speeds for clients with certain limitations typical of cheap gear) and what actual throughput you can expect in any of those cases (about 50-60% of the above numbers).
802.11n has provisions for operation up to 600 mbps signaling using APs and clients that have 4 radio chains (supporting 4 spacial streams, sometimes denoted as "4x4:4"), but note that no one has shipped 4x4:4 equipment yet.
In late 2009, 3x3:3, 450mbps 802.11n equipment started hitting the market. Apple's late-2009 refresh of the AirPort Extreme and Time Capsule supported that. Apple's "Thunderbolt" refresh of the MacBook Pros and iMacs in spring 2011 also supported that.
Your Netgear WNDR3700 N600 is only a 2x2:2, 300 mbps product, so it's no faster than the earliest draft-N gear from late 2006. But at least it's simultaneous dual-band, which is nice. I think that simultaneous dual-band 2x2:2 gear generally hit the market in 2008.
Also beware that 802.11 has lots of overhead, so the rule of thumb is that your TCP throughput will only be about 50-60% of your signaling rate, and you only get the best signaling rates when you're relatively close to the AP with no interference.
As for Question 2 (Range), you'll be fine. You probably won't get your top signaling rate throughout your apartment, but you'll get decent speeds. Remember to leave all the data rates and technologies enabled on both bands so that your clients can choose the best bands and rates to use for best performance at range. That is, leave b/g/n enabled in 2.4GHz, and leave a/n enabled in 5GHz. Don't be tempted to force either band to "N-only" (or "G-only" or "A-only") because that actually just limits the options for your clients, making them less capable of providing the best rate at range.

for gsam , after last update when I started it asked for more privileges, like I was root but I'm not root so with adb command that I don't remember now it seems that is fixed
for wifi now I set the router to N only and width 40MHz (2 options 20 and 40) but I don't know why the honor 8 connects at 20MHz and Is the only device doing that, walls and other objects are not the problem, the phone is only 20cm away from router

20 & 40Mhz at whatever (N say), can allow 150Mb/s for a client. All 20 and 40 are are the space between channels within the band. For a lot of concurrent clients all going like nuts, the wider the better, but for one two or three, not a biggie.

my wifi works fine, i pick up mine about 6 houses down, ill do speedtest in a min
Has anyone observed a difference in wifi speed and signal strength between midrange and flagship phones? I just bought a Samsung Galaxy A71 to replace my Asus Zenfone 3, both midrange. Neither of them achieve the same wifi speeds across my house as my wife's iphone XR. Is the integrated antenna lower quality on midrange phones? We have 300mbps internet (can hit that speed wired) and an ac3200 router, in one weak point of my house the two android phones get around 75-80mbps on a speedtest whereas my wife's iphone gets 150-200mbps. Haven't done a test from the backyard as yet, but I know my asus can't connect to our 5ghz wifi and falls back to 2.4ghz, wouldn't be surprised if the samsung is the same.

I agree with snap in fold, Exynos is problematic but previous I had few samsung phones with exynos high and mid (Note 5, A8, A5, Note 9, N20U) and I have first time similar problems a lot of time with cellular like in S22U.
So after that I supposed hardware defect in my device. Only thing what can I do is sent to service for replace motherboard or happily all device.
Services in my country are problematic and usually first flash soft via odin then sent back but I must try.

I found many references to antenna problems in the web for this phone. I think that probably it's a well known problem; probably a HW failure in the antenna. I would send it to repair.
I send it to repair yesterday but i dont know if they found the problem or they just send it back and say that the phone is okay

The last direct SD/Exy comparison I did myself was with two Note 10, it was frequency dependent. +- 3dB on one and +-3dB on the other. Therefore I started wondering why it's that extreme on _Grizzly_s device.
In addition he says his Note 20 was fine regarding signal quality, the S22u not (I assume both Exynos). If I check dBm values measured in the Weka lab, I see:
N20U TX
GSM
20,4 25,4
LTE
17,2 18,9 17,6
N20U RX
GSM
-98 -105
LTE
-95 -96 -93
S22U TX
GSM
21,6 25,4
LTE
17,2 20,0 18,5
S22U RX
GSM
-100 -107
LTE
-95 -95 -92
Therefore my assumption would be that his S22U has a defect.
