Re: TT - Tech Talk (Computers, Laptops, Tablets, Mobiles, Devices, Systems & Software
Am facing the issue of my Galaxy Grand Quattrao Android phone getting frequently disconnected..... My router is o.k, as the laptop is connected to the internet. Looking for solutions, I found many on the net (As mentioned - Know very little of tech)
So posting the best of solutions - which I have to try out on my mobile....

If your Android device constantly disconnects from Connectify Hotspot there are a few easy ways to troubleshoot the issue. Usually, when you’re having problems with a device continually disconnecting it’s an issue with your wireless drivers, but that not always the case. If updating your wireless drivers didn’t help the situation, then try checking the settings on your phone.
Most newer Android phones and tablets will attempt to test the Internet connection when connecting to your Hotspot. Sometimes, however, they may incorrectly detect a poor Internet connection when the connection is perfectly fine. You can disable this feature in your Android device by looking under the Advanced Wi-Fi settings for the option that allows the Android device to automatically switch away from a wireless network if it thinks the network is bad. There are lots of different names for that option on different versions of Android, so try looking for something along the lines of:
• Avoid Poor Connections
• Auto Network Switch
• Smart Network Switch
Once you find that option, simply disable it by switching it OFF. With your Android phone no longer misidentifying the quality of your Connectify Hotspot, the device should stay connected properly.

It may be due to other (open) WiFi signals "disturbing your device". With multiple APs being available (in range), your device might try switching to the strongest signal. Of course this would require your device had been connected to them before (Android doesn't automatically connect to "unknown" networks – but it does automatically connect to networks you've used before).
If there are networks in range you've used in the past, you could try to remove them from your "known networks": Go to Settings › WiFi, and check which networks are listed. Tap-and-hold each of them will reveal a context menu allowing you to edit or "remove" it. Chose the latter will tell your device to "forget" it has been connected here already, and thus to not automatically connect it. Just leave the one you want to use being "known" should rule out this cause.

The problem lies in the DHCP settings of the ADSL router Login your router and go to DHCP settings and find the item called " leasing time " The default values of the "leasing time " is usually "Forever" and this is the bug with Android
All you have to do is to change the value of the "Leasing time " from "forever" to any other long value (depends on the routers options). Here i changed the value from "forever" to " 2 weeks " and since then i didnt have any single WIFI disconnect

Try your phone at other hotspots and make sure that its WiFi is actually OK, as it’s always possible that there’s a loose contact or some other problem there!
Assuming it’s not the phone, it could be intereference from other WiFi networks. You can install WiFi Analyser on your phone to see which channels are currently in use (there are similar packages for PC too, but I can’t remember their names at the moment), and see if your router is “competing” with others, then change your router’s settings to use other channels that are free. Your phone may simply be more sensitive to WiFi interference than other equipment in the house, which is why it is more prone to disconnect.

If your ISP has given you static IP,then you would have to keep the Best WiFi option enabled. If your router doesn’t supports 5GHz and,select 2.4 GHz frequency band or see whether there’s an option to detect automatically.
Configure your WiFi network by going to Settings –>WiFi and keep constant tap the name of the WiFi network you are connected to.A popup window will appear to either to forget the network or modify it.Choose to modify.
Select the checkbox saying “Show advanced options”.
Change IP settings from DHCP to Static.
Now,input the values of the remaining fields that you can see.
If the above solution still doesn’t helps,then try using AES encryption method instead of TKIP.

1. Log into the router with admin rights.
2. Click on the Advanced tab at the top
3. In the left NAV pane under Setup, click QoS Setup
4. In the WMM tab, Remove the check marks for (1) Enable WMM settings (2.4GHz Bb/g/n) and (2) Enable WMM settings (5GHz a/n)
5. Click the apply button
6.
The apply will take several seconds (I think it was less than a minute), proceed after the apply finishes. On the tablet, turn on the Wi-Fi (you need to be in the settings). Find your network, tap your network, select Connect (supply the password if necessary).
At this point lots of stuff that was queued up started to download to my tablet and now all seems to be OK.

Noise Any other energy at frequencies used by your connection. This includes other WiFi devices but also other things like microwave ovens and wireless phones. You can try to set your AP to a channel that has less noise. The nonoverlapping channels you should set a 2.4 GHz WiFi AP are 1, 6, 11, and if your country allows, 14. In general, there is less traffic on 5 GHz channels, so these are a good option if supported by the AP and phone. Your AP may have an option to automatically change channels if it encounters a lot of noise.

Restore the phone’s factory defaults, and it will do fine.

I had this problem with one of my routers until I updated its firmware. See if there is a router firmware update first.
***
Go into settings-wifi- then uncheck 'smart network switch'.

I've resolved my issue by deleting the connection and then reestablishing it.
