OK, there have been plenty said about various devices having issues of random WIFI drops during good signal conditions.
I have learned long ago that there are some devices that do not play well with legacy Draft N routers and modems connecting to newer WIFI devices that have power save functions.
This issue is primarily with the advanced features within the Modem/Router WIFI features.
Here are the two features that can help with connection drop-offs.
DTIM Interval
Beacon Interval
If you set DTIM Interval to low, you risk flow condition drop-offs. Some people find a value set around 6 to be effective for both gaming and file transfer.
The lower the value the less power is consumed in the WIFI connection. Small devices with smaller batteries need a low value, like 1 to 2. If you have a good sized battery 6 to 8 will work well.
Beacon Interval will create a high level of repeated instances of beacon synchronization, if using WPA security. Which can augment the delay between data stream. If you find yourself in an area of about -80db and drops are noticeable, decreasing the time in between beacon intervals will not allow time to recover. Once authentication breaks, you will need to reset your devices WIFI enable to regain authentication. Changing the interval to 200 to 300 ms will help. But when your interval is set at 1000ms intervals, it will make your issues more problematic.
I keep my numbers one the edge much as possible, so peeps outside my house find connecting extremely difficult at -90db
Many have circumvented the above issues by using WEP or open authentication. Which is only a band aid fix.
Channel congestion can make drop-offs. As it slows your data path and can make extra authentication cycles during recovery.
Before making any changes copy down the original settings for restoring them if needed.
Some apps I am using for my WIFI connection.
WIFI Ace (WIFI Advanced Configuration Editor): Will attach to advanced WIFI hotspots, including none broadcasting SID.
WIFI Fixer: Automatically reconnects during any drop-offs, and will restore connections after sleep cycles.

can anyone build a kernal that improves the wireless.

I did something that improved my wifi stability by a huge amount. it doesn't even drop anymore. all I did was to go to the router's settings and modify the "Fragmentation Threshold" and "RTS Threshold" from 2346 bytes to lower values untill my wifi connection was steady. I'm using the almost lowest values allowed. The router now sends smaller but stronger packages more often and it should be better. please tell me if it works!
My wifi connected was droping after 3-4 mins usage. When I am opening wifi I also open bluetooth, now it does not drop.

Sorry I'm a noob here so pardon me. How do you access the 'router settings' in the phone and how do you determine what are the 'lowest' values that I should set? Thanks!
LOL! @goldenstarlz93. Not from your phone. sbr999 was talking about if you have a wireless router set up at home. If so, log in from your home computer and access the router's homepage using your web browser. (It should be something like this http://192.168.1.1/ ; although it could be different for your router).
Currently trialing CM9/Franco;
Anyhow, whilst streaming data (SIP/streaming radio/etc) connected to wifi after leaving range of the AP, there's a drop (audio) while the mobile data connection is reestablished (?). SetDNS has a notification pop of the changeover to the dns servers used by the hsdpa ap, so I'm guessing that it's resolving a new address every time that wifi is detached?
Is this normal behavior for ICS/android as a whole? Is there any method to keep active on the mobile data side, wifi on and preferred, so when one leaves the wifi area the changeover is relatively nonexistent rather than the 5-10 seconds at hand? That's enough to kill a phone call
I'd imagine that in some sense something is retained for the sms push, but I'm guessing that's...well, separate.
Of course there will be a break in streaming switching from WiFi to Mobile data, unless the app uses a large buffer and you're on a delay.
When you're on WiFi, Mobile data is turned off. Keeping both on would defeat (or worse) the battery savings offered by staying on WiFi. Both running at once wouldn't help anything.
You're not going to be able to hold a SIP call between WiFi and Mobile data, you won't be able to consistently get a quick enough handoff to do that. Keep in mind that for things like WiFi calling on T-Mobile devices, they needed a completely separate chip in the phone and specialized software to handle a phone call switch from WiFi to Mobile network seamlessly. That just gives you an example of the extra hurdles it takes to do something like that.
Seeking advice for the most efficient WiFi Access Point configuration on the vzw m7 - native CM11 WiFi AP vs. the Mobile Hotspot in NuSenseSIX; optimal CPU governor and other kernel options, etc.
I'm doing an experiment to see if it's feasible to use my vzw unlimited data plan and HTC m7 for all of my phone and Internet usage (personal and business usage). I work primarily out of a home office, and my LTE service at home is very good. It actually has more bandwidth than my landline ADSL+ service but with higher latency.
The problems thus far:
battery usage - it drains really fast and charges very slowly when using the mobile AP (kernel optimizations, etc?)
latency issues tend to annoy VOIP applications (can this be tuned or is it just what is?)
AP setup and teardown - since the AP needs to be active when in the vicinity of my home office, but ruins battery life when I'm out and about, I'll probably look to use tasker or something to fire up the AP when needed - suggestions welcome on the best approach
I'm not convinced I can cut the proverbial cord yet, but it's feeling like it may become possible soon.
Here is a fix for the crappy slow useless GPS on the ascend mate running 4.2.2 this may work on other Roms too!
you will need https://play.google.com/store/apps/details?id=com.chartcross.gpstest&hl=en_GB
1. Download the app topnt from here http://forum.xda-developers.com/showthread.php?t=2198319 and select settings as follows global -derek gordon- generic- google select install but do not reboot!
2 . open keypad dialler and dial *#*#2846579159#*#* then select 6 background setting, then 7 agps setting, then as follows
LOCATION METHOD= MOBILE STATION BASED
NETWORK USED= ENABLE A-GPS FOR LOCAL NETWORK
DATA CONNECTION .. DONT CHANGE THIS SETTING
SERVICE ADDRESS supl.google.com
service port 7275
Then exit and reboot and enjoy I get a fix in less than 8 seconds now!
MS-assisted mode
Assistance data sent to the mobile for every fix; the only hybrid mode
Has the greatest GPS sensitivity
Supports fall-back, backup position solution types, such as AFLT, thus maximum yield
A data call is needed for each fix
Fix computed by the PDE server
Best suited to applications requiring less frequent fixes, or maximum sensitivity:
Slower tracking applications
Fixes required in challenging locations
MS-based mode
Assistance data sent to the mobile periodically on an as-needed basis
Mobile measures GPS pseudoranges and makes position calculation
Uses only GPS satellites
Shortest latency between fixes enables rapid repetitive fixes for tracking and navigation
Only needs occasional data calls
Fix computed by the handset with occasional PDE server assistance
Best suited to handset-resident applications, particularly those requiring lots of fixes
Turn-by-turn navigation
Fast tracking applications/geofencing
Standalone or autonomous mode
No assistance data at all
Mobile performs all operations with no assistance at all
Increased Time to Fix and battery consumption
Diminished yield and accuracy
No data calls needed
Fix computed by the handset only
Best when out of wireless network coverage
I have a question. I have "keep WIFI on during sleep" option set to "Never".
-1. Wi-Fi is enabled. I put my phone to sleep.
-2. When I wake up my phone from sleep after 30 minutes or more of not using it, the wifi does not reactivate itself (it's off, no icon in statusbar), but when I go to settings, it says that Wifi is enabled. (look at the screenshot below)
I want to know if this is normal or what ? I am currently on stock Nougat, but this issue was happening to me even on previous Android.
Can someone please test this, I wonder if I am the only one with this problem
This should not be a issue. Since i even got warm about a thing called DFS in terms of WLAN. Check your routers log about a thing named similar: "DFS wait time".
If this was triggered you have to wait until they finished communicating and this would not have to do anything with your phone. That would be router setup related then. E.g. your WLAN's channel is to be freed by force in this special case.
Try statical in 5 ghz: 36 to 48 (not affected by DFS) e.g. 36 40 44 48
Be aware statical is not optimal and these channels are not optimum for high bandwidth.
It says "Tap to select network" meaning the network you were in before is not there anymore or has changed, out of range, gone to sleep - reduced bandwith since unused from router side possible?
Try additionally delete known network and add freshly and new.
