Galaxy S2 and D-link Router eating battery

When connected to my D-link Dir-655 Android OS is running cpu constantly. This is not a problem when connected to other routers, so I am wondering if there is anything I can do to fix this.
Is there any settings I can change on my Dir-655 so I can use it with my phone without running out of battery in no time?

Not that I know of. FWIW, I've had problems with the DIR-655 connecting to other wireless devices; it's bad enough that I had to switch back to my old WNDR3700.

I got a new router and gave the old dir655 to my sister and husband lol
Got a billion 7800n works well not as much drain, i also use juice defender to stop wifi when screen is off. they work well together i set jd to basic

I have a Dir-655.
Had 10%/h idle drain and 0,3%/h after i installed Juice defender pro.
Cheaper then change router if it helps.

Using the exact router and I just checked. Connected via WiFi and just left the phone and the processor goes back to idling. I use System Panel to monitor it. Which firmware version are you using?

Funny i just installed a new Dlink yesterday and also had noticibly bad battery since however I just thought it was down to the latest firmware

How long did you wait for result? more then 5min in idle?
I use watchdog and after 5min it always shows two processes go berserk.

No I stopped after 3. Maybe later I'll check again.

I have the same problem

KE7 on S2 and on Dir-655 I have tried the newest beta and the two EU versions before the beta I use now.
To day I got an WNDR3700, used the same SSD og password as on Dir-655.
First I was connected to Dir-655 for two hours with the phone idle. Android Os had 1H 45M of cpu time.
Then I connected to the WNDR3700 for another two hours with the phone idle. Cpu time went from 1H 45M to 1H 49M.

Please do Let it be connected and idle for about 10-20 minutes

I was just using WiFi for 45 minutes and didn't have any issue. Phone is use XWKE7 firmware and Router is using 1.31EU, router is revision A3.

My Router is revision A2.
Android OS did not use any cpu time when you were connected?
I have talked to several others that have the same problem with S2 and Dir-655.

I did a little test today before throwing away my Dlink router.

WPA2 with AES, firmware 1.31EU, router revision A3.

A couple of us have Netgear routers. Specifically N600 and N750. I actually get better battery life using Wi-Fi than I do using 2/3/4G. The SGS2 appears to be very router sensitive.
This was overnight with Wi-Fi enabled:

I just updated to the 1.35 EU BETA 2 firmware on the router and will see how that works out.

5GHz WiFi dropping

Anyone else having this issue? My tablet will randomly stop seeing my 5GHz network, other devices aren't having this issue, and it's still seeing 2.4GHz networks.

Try changing the channel manually in your router settings. Some mobile devices are really picky about this...same issue happens to my gf's Galaxy Nexus. I don't own this device yet, but this is some general advice that I'd try first.

Mine is similarly having trouble connecting to 5GHz networks from time to time. It seems that when the tablet set to 'auto' it stops scanning for 5GHz networks. If you manually set it to 5GHz it will immediately find the network. Hopefully there will be a bug-fix.

check your routers 5Ghz settings. Make sure you have it on a 20mhz channel if given the option as 40mhz or hybrid 20/40mhz will usually give you connection errors.

dont set auto, try manually and check router settings, it could be help to fix bug

Haven't connected mine to 5GHz on either of the dual band routers at my house. I always just use 2.4GHz with all of my devices. I'll try them both in little bit to see what my results are though.

The issue I think is that 5GHz is not nearly as effective at maintaining a strong signal through obstructions like 2.4GHz is. I only get a 2 bar signal in a room on the other side of my router while I get a 4-5 bar connection strength with 2.4GHz in the same room.

I was having trouble with 5Ghz too (I was using 802.11a). In order to even get a stable connection, I had to change channels on the router. But as previously noted, it does seem that it has more problems with obstructions. I sometimes lost connection with just one wall between me and the router, but with 2.4Ghz, everything was fine.
I have never had this problem with my GS3 or with any other phone that I've used on 5Ghz.

I think higher frequency in general is harder to penetrate obstructions. Same with my 5Ghz on both my routers. Will have to change the channel to see if it helps my connections. I leave it on 'auto'

Not having any issue connecting to 5ghz band. It does get a little weak when upstairs but has not dropped.

I was seeing 25 MBS down the first time I connected to my 5ghz, and then it dropped it one day and never showed up until I reset my network and now I'm only getting 8, 12 if I'm lucky.

You saying you were getting faster speeds on 5GHz than you do on 2.4GHz? Or were you just mentioning the speeds because it's now slower on the same 5GHz router?

I would normally only get 8-15 on 2.4ghz on my tablet, and I when I went to my 5ghz network, it was set to auto on the channel width And for some reason it knocked off and I couldn't join again. After I reset it, I was only getting 6 mb on the 5ghz. I just changed it back to 20mhz channel width, and it's flying. 64mbps link speed, and 24mbps down, 2.80 up.

If youre in the US or canada, Check your WiFi settings, many are reporting their tablets being shipped with wifi region set to Europe. Europe uses slightly different settings then the US and Canada.

I have had issues with my N7 dropping signals altogether. I have one router (upstairs) w/ 5ghz and another (downstairs) on 2.4ghz. My N7 doesn't even see the 2.4 and will occasionally drop the 5 and rebooting won't fix it, nor turning on airplane and off.

Have you used the same SSID on your 5GHz as on your 2.4GHz?
If so: they must be different!

My Note 3 Work very well on 5 Ghz, is my wifi at home. Router Belkin.
Look whit Wifi Analyzer, option wifi channels. You see all of the 2,4 Ghz, and if You touch on top left it change to 5 Ghz. You must see Yours.

My N9005 connects to my Asus RT-AC66U, but keeps complaining about an unstable internet connection. My old SIII worked fine. Compatibility issue between N9005 and Asus AP's?

Did you find a solution? I have the same pproblem.This plus the unstable connection problem is making me miss my note 1

Found this link http://forum.xda-developers.com/showthread.php?t=1675547 on 5ghz connection issues on Note 1 in Hong Kong. It describes channel limitation based on region. The file in my etc folder has ccode=GB which I assume is Great Britain. However, it allows the channels that my wifi router EA4500 is using on the 5ghz channel. So no luck on recognizing the 5 ghz network still.
I downloaed wifi analyzer and looked at my network. By default my router and I assume all the ones in my neighborhood use channel 1 on 2.4ghz. I just switched to channel 12 and there hasn't been any issue for the past hour i.e. no unstable connection warning from the phone. Just downloaded a 40MB file without any glitches at good speed. Will report back if the problem comes back.
Edit: Spoke too soon. Unstable connection warning back in a couple of hours. The interesting thing is that both my old Note 1 (N7000) and my wife's S4 can see and connect to the 5ghz SSID just fine and of course have no unstable connection notifications which seem to be an 'enhancement' in the note 3! Sigh Haven't even rooted the N9005 because of the knox flag or I would have played a bit with the wlan configs in the etc folder. Guess will have to wait for Samsung to come around to admitting a problem and then fixing it.

I've been having the same issue with my RT-AC66U.

I also have a RT-AC66U... and I'm connected fine with my Note 3.
go into your wifi settings and make sure that the third checkbox is not checked.
Name in french of this box is "Basculement réseau auto"...
With this setting enabled, my wifi is unstable even if the signal power is full.
Also make sure that you have the latest firmware on your router.

Try channel 48. Dont use those channels 160+, may not be supported.

Thanks, I had same problem with my Note 3 not finding 5ghz and switching the 5ghz channel to 48 did the trick.

why is wifi speed getting slower?

everytime i try to download something or use internet on my phone, the wifi is toooo slow.. but when i turn off the wifi and turn back on,
then i get higher speed. but after a while it will decrease again :/
i have 150mpbs internet
i9505 S4 omega v28 4.4.2 (before this had 4.3 pyrana was also same)
any ideas?

Or it's your router or it's your modem.

problem in your router

there is nothing wrong with the router, making tests also with my wifes s4 mini but it never happens.
if i dont use the phone for a while, then do something, the wifi speed is really less.
then i reconnect to wifi, it works good
see the last 2 tests please

It's maybe a combination of your router and the s4. You can easily test this when you are connected on other wifi's.
Or maybe it's solved when changing your modem. It's the one or the other.

Why don't you check your link speed that you wifi is actually connected to you're router? Just cause you got a 150Mbps router doesn't mean the link speed is 150Mbps. Within 6 meters of my crappy telstra (technocolor) router which is 300 Mbps gives me a link speed of only 5 Mbps @ g mode.

1. Reset your router. Unplug it for like 30 seconds then plug it back in.
2. Set best wifi keep options to Keep Connection and Boost Signal
3. Forget your wifi connection on your phone
4. Reconnect your phone to your wifi

Slow WiFi Speeds on Z5 compared to other devices

Over the past day or two I've noticed the download speeds on my Z5 to be slower than my other devices on WIFI. I'm not sure if it's cause and effect or just a coincidence but my phone fell 2ft/70cm when it slid off a table and fell onto timber flooring landing directly on it's back.
The phone has a case but I've done a factory reset and the problem still persists. Perhaps I've damaged the antennas but my mobile data appears to have had no change in speeds. The speeds varied on my phone over these 2 days ranging from 1-3mbps compared to the normal 6mbps i get.

Check your modem/router frequency that it use to send out the WiFi signal, and if you can change the frequency of your modem or router then change it to something else and do a Speedtest.
With a app called Wifi analyser you can see which frequency band is best to use when you connected to your Wifi.
If none of the above steps helps, then I have no idea what it could be, my Wifi works great anyway, getting 11 mb/s download speed from my modem.

Yep same as you, in addition if other devices are connected to the same band at slower speed they will also kill the speed of any other devices on that band

No the case won't affect this, in addition what are you actually talking about, your speed has gone to crap accessing files within your network, or are you talking about the internet. Because there are so many variables that can affect internet speeds, and a huge percentage of them are fully beyond your control.

I ran some speed tests at a friend's house to see what was going on and it seemed to show similar speeds against my friend's devices also connected on WIFI. I'm suspecting it to be a problem with my router but will run a few more tests with a borrowed router.

I am having problem with wifi, it says connected, but no internet access.
This is happening lately, mostly after last update .182
I don´t know but since then I have restarted my router for three times now, on laptop I don´t have any issues.

Speedtest gives me 219/200mbit/s on my z5 compact, could be better but it's acceptable for a phone

Other than home (which does not have any issue) I do not connect to other wifi. But on my recent travel, i've had the same issue as you connecting to various places which has wifi. I believe its due to router settings mostly.

I'm getting the opposite - mine's a disconnection issue. No WiFi connection issues but when I leave the house my E6653 sometimes fails to drop the WiFi connection for mobile data so I'm miles away with "Connected, No Internet" with a bang (!) next to the WiFi icon for my home SSID - far out of range! Turning WiFi off and on again sorts this out, i.e. mobile data connects instead.
Anyone else?

It seems fine for me but bluetooth and wifi on at the same time causes some imense lag.

My Z5 has BT on 24/7 (paired with smartwarch 3) and no WiFi lag.

Don't use same name on the the 2 networks, and make the ipcams connect to the 2.4GHz band.
Eg: 2.4GHz is named [email protected] and 5GHz is named [email protected]_5GHz, also disable band steering (if your router/ap supports it) if the cameras are supposed to be 5GHz "compatible" but actually don't work on it.
