Wifi hangs

I have a problem with wifi since I had bought my htc dream..
I connect to my wifi network and all goes well.. I can browse internet, market, and so on.. But after some minutes it begin to hangs.. If a wait for some times it returns to normality, but after some minutes the situation is newly bad..
Wifi work/does not work/work/does not work.... and so on..
Is someone having the same problem?
How could i resolve?

What are your specs?

What do you intend? My router?
It is a michelangelo wave..
It perfectly works with my wii, nds, eeepc, iPod touch.. Only with G1 I have problems

My bad what are your specs on your phone. I'm assuming your rooted, but what rom and radio are you running?

I'm running latest experimental cyanogen + latetst spl (the one used to run hero)
However I always had this problem.. Changing various roms and radios..
rc29 (or uk correspondant) adp1, adp1.1, various jf, hero rom, the dudes, various cyans..
Always had this problem

Does this issue only exist with using your Wifi at home? As in your router? The G1 has some known issues for not connecting or hang time with certain routers. I myself have somewhat the same issue you have. I have a D-Link DI-614+ wireless router (old as hell but hasn't failed yet). Weird thing is only my phone will not connect to the router unless i do a soft reset via internal, EVERYTIME i connect my phone to it.
My guess is that your router may be the problem here, not that there's anything wrong with it. Try going to an area with a wifi hotspot or try borrowing a friends router to see if your phone acts any different. Starbucks, library, etc.
Otherwise, try messing around with some of the settings of your router. Because I've never heard of your router so I wouldn't know what to recommend for it.

Yes, the problem is only with my router.. I asked to know if someone managed to solve it..

Can you post the specs on your router please.

Have you checked to see if there is an update for your firmware for the router. Also I see its 802.11b/h. I was reading that some people were having problems with wireless "n" and had to revert back to "g" for the g1 to operate properly. Have you tried changing any of the settings in your router to see if that would effect it at all.

I tried, but I actually don't know exactly what change..

You tried changing your settings on your router or firmware. Just tryna make sure I'm on the same page. I don't know if I over looked it in the post with all the specs on your router, but what is your routers model number.

What do you intend with model number?

It will help with troubleshooting.

Sorry but I think it has not a model number. Like for example HTC P3450..
It is just "Digicom Michelangelo Wave"

[Q] [POLL] WiFi ping and jitter

Hi Everybody!
Trying to use sgs as SIP client (CSipSimple).
I have to use only! G.711a codec. G.711 is good enough but doesn't like packets loss and jitter IMHO
So I setted up everything, everything works, but not perfect for me.
Investigation I started shows me that ping to my WiFi point (from SGS) is in range of 20-50-70-100-200 and even 1000 ms and realy not stable. At the same time. ping from notebook connected to the same WiFi point as stable in range 1-2 ms.
Ping from accesspoint to SIP proxy is very stable, quick and 100% lossles!
Using ROM Darky 7.6
WiFi point D-Link DIR-320, latest official FW.
Was trying change encryption method (or switch it off) and other settings - almost no effect.
So, peopple, please - check your wifi connection quality and post here.
Going to find - what is it? - ROM, SGS hardware, WiFi accesspoing (hardware/software) or else....
Thanks in advance!

[Q] Is there an app or method to tell if you are connected N or G wifi?

I am trying to troubleshoot my router, it does b/g/n
I have it set to g/n
I want to know if there is a way to tell whether the cappy is using the G or the N radio
I cant disable G, I need both on but I would like to see that the phone is using N if it can

quite simply, if the router you have isn't dual-band and is just using the 2.4GHz range and NOT the 5GHz range, then yes, your phone is connected at wireless n. but just because you have a theoretical max of 133 Mbps (or 300 Mbps if you bought the router within the past 6 months) doesn't mean that's the thoroughput you're going to get.
likely, depending on where you live, your internet connection tops at about 10 Mbps (that's megabits, not megabytes)... some places (especially if you have fiber) around 50 Mbps...
so realistically your phone is likely maxing out any downloads at about 2 megabytes a second... 10 if you have a really fast connection.

I am not asking due to speed
I am asking
Is there a way to tell what type of network your wifi is connected to, b/g/or n?
not just to my router, but anytime I am on wifi
on the phone?
on a XP?
on Mac?
PS
DD-WRT shows channels higher than 11 so those must be the 5Ghz channels
it is a WRT300N btw

the cappy doesnt have a 'n radio' and a 'g radio'
the cappy has an 'n radio' and 'n radios' are backwards-compatible to pickup older signals
you set your router to output g/n signals, your recieving device will pick up on the fastest signal
to test it, look at your data speed,
in windows click your wifi in the corner > status > SPEED
on your phone... Menu > Settings > Wifi > click your network > Link Speed
mac... i dont care.

Think that router didn't allow for auto switching between 2.4 and 5Ghz channels. You have to select it, so the one you select is the one you are using.I font think Lynksys starts auto switching until the 400N. On other networks,.use speedtest. Anything over 5.6mb (i think) is n speed.

[Q] wifi speed on lg 2x - 1mbps?

Hi!
when im downloading files from pc to phone using wifi/astro-samba im having max 1mbps speed. is it considered to be normal?
host pc is conected to router by lan
router: Netgear WNDR3700, b/g/n, WPA2-PSK [AES]
any hints to increase dl speed?
phone: lg optimus 2x, cyanogen nightly 11x

When I upload a file to another computer from my phone on my network the speed is 1,5 MB/Sec. The computer is on LAN, same as you but a D-Link router..
Download speed I don't know, probably the same

What's the distance to the router? The speed changes a lot with the distance. If I put the phone next to the router, I've reached speed of 4-5Mb/sec (600Mb in 2 minutes).
Regards!

Well... windows file protocol, aka samba, is probably part of your issue. It's a piece of crap
Throught rtorrent, my phone was downloading at 600kbits/s ....

Me too. I got fiber home and I easily get the 25mbit I got, both ways. Through one or two walls to actually.

my speed wi-fi (use ftp\smb)
PC (D-Link DWA-140 RangeBooster N USB) -> LG O2x = 7-8mbit\s
PC (D-Link DWA-140 RangeBooster N USB) -> GPAD GFORCE = 14-16mbit\s

G900-F real life WiFi 802.11ac performance benchmarks

Hi all
I couldn’t find detail benchmarks of S5 implementation of Broadcom BCM4354 2x2 MIMO 5G WiFi 802.11ac module and in the end decided to take u plunge and purchased Asus ac68u router. Went thru setting up 5G ac wireless network and current results look like this:
S5 connects to 5G ac network with link speed of 866Mbps
File copy from:
Gigabit LAN wired PC to Routers attached USB 2.0 HDD 29MBps (240Mbps) - bottleneck usb 2.0 interface
5G ac WiFI S5 internal storage to Routers attached USB 2.0 HDD 11 MBps (90Mbps)
5G ac WiFI S5 sandisk 128GB microSD card to Routers attached USB 2.0 HDD 11 MBps (90 Mbps)
I have 100/100Mbps broadband internet connection and S5 on speed test performs as follows:
72Mbps DL / 75Mbps UL (same connection via wired PC benchmarks at 94Mbps DL / 95Mbps UL)
I haven’t managed to achieve transfers speeds above 100Mbps from or to S5 in any combination. Can you please share your experience of S5 wifi ac 5G network performance
Related : thread by xenokc about S5 performance on 802.11ac network
Thanks

can you test with no encryption? wep/wpa completely off.

Yes, i have tried that, but there was no change. Router firmware is upgraded to the latest version / wireless test were done in close proximity (1 meter) to the router without any physical obstacles between (clear line of sight)
I'm really on a mission to achieve transfers speed in a range of 350Mbps-400Mbs on local LAN (which should be doable) but i cannot get pas 100Mbps!!

i'll try to test as i know AC should be able to do it.

802.11 ac provides a theoretical maximum stream speed of 433 Mbps or 900 MB/s across eight streams. That is under ideal conditions - maximum signal strength, zero interference, zero processing overhead and zero packet overhead. Many router 802.11ac chipsets only support four streams and due to real life channel contention, you aren't likely to see more than two or three 160 Mhz channels chopping that maximum speed to about 250 MB/s. All of those speeds assume channel bonding and quite a few routers can't bond 80 Mhz channels cutting that speed in half again (125 MB/s). Then you have real world losses due to signal attenuation, antenna inefficiencies and interference.
The S5 was the first smartphone to support two MIMO streams. But two is not three, so lop another third off our speed figure (or lop two thirds off for the iPhone 6 which only supports one stream). You simply won't achieve your goal with the S5 or any other current smartphone. 350 Mbps is the upper end of the maximum speed you might expect to see from a high end MIMO PC card under ideal conditions in the same room.
In real life and through a wall, you should expect considerably slower transfers. And the type of traffic matters too e.g. TCP traffic overhead often reduces speeds three fold over UDP streams in router speed tests.

Thanks for detailed feedback, but then there is no benefit from implementing ac standard or 2 spatial streams suporrted by broadcom chipset when performance is comperable to WiFi n standard? But then again how did those guys here managed to pull of such results:
382MbpsDL
or
436Mbps
whit same hardware setup?

..

what kind of latency differences did you see between the wifi phone and your pc to the same server? i'm assuming speedtest.net or something like that?

This is strange as for my G900I I've been able to run an Internet speedtest at over 11 MBps (88mbps) over wifi on wireless N at my university which I imagine would have multiple connected devices. Wireless AC should be able to at least match the 88 mbps I had achieved.

No, don't do this. You must setup a WPA2 security encription to get maximum rates on WiFi N and AC.
Then, remove storage bottlenecks. Don't use a external HDD connected to a USB2 port. Much less on the same router, since USB performance is much lower on those devices. You will need to use 2 devices on the same LAN. One wired for maximum throughput tests. A ramdisk or a SSD on the host would help too, since HDDS are limited to 120-80Mb/s transfer speeds.
If you are going to use a file copy as measure, make sure you make it into the internal SD card of the phone, since external will be limited to around 8-12mb writes depending on the card quality.
To test networks you would need ramdisk to ramdisk copies, but I don't know how to setup this on android.

This is rather interesting to follow

iPerf is available on android.
Quick measurement gave me ~110-169 Mbits/sec using default values on 40mhz WiFi N 5ghz setup.

Thumbs up. Finding someone that uses IPERF for measuring proper network performance is golden. It irritates the heck out of me to find video's of people using ookla to measure their network speed, or like the OP, measuring against USB2. That's like measuring the speed of your new 600MB/s SSD installed on a SATA 1 controller and wondering why you are not seeing a significant improvement.

iperf is a little more complex than ookla though, and thats usually why. same reason most of us dont compile our own custom roms
really, there isn't much need to get over 100mbs on wifi for 90% of the public.

Just picked up the s5 because no store will sell me the note 4 retail price.
Linksys WRT1900ac stock firmware, 5Ghz a/c connected @ 300Mbit
From the phone to wired linux box @ 1000Mbit
187 Mbit up 207 Mbit down but of course it fluctuates. I don't use wifi for anything that requires that much bandwidth anyway, but I do get my full internet speed of 175/30 using the phone.

This post is rather old, but some of us may still be interested.
I was looking for an alternative to usb cable to transfer files fast between a pc and galaxy S5..
I've used a wifi-300 stick connected to usb port on PC: TL-wn821N, and configured my S5 as a mobile access point.
An ftp server is running on the phone and an ftp client on PC. i am accessing the AP via AirmoreAP hotspot, with wpa encryption.
I am watching the download rate via crystal internet meter for windows.
And this is the result: 64mbps/56 mbps (DL/UL) UL reading a microsd card on phone and writing to sata2 internal disk on pc.
I am wondering if I can reach much faster speed with a wifi-ac stick.
