I have had problems with a dropping internet connection since day one I had the Ipad. I did a lot of reading and found a lot of suggestions. The strange thing is that according to the answers for some people these individual suggestions helped. In my case unfortunately they did not.
I will try to list done all the things that I have read and or tried myself. If you feel up to it you can try them yourself. Since many threads handle this subject I would appreciate it if you only mention if a certain solution works for you. Not if it doesn’t. If people have other suggestions please feel free to add them.
Before trying anything below make sure your router has the latest firmware.
Reset Network settings
Settings/General/Reset/Reset Network Settings. This will NOT delete your apps, music, etc.
Press simultaneously the power and home button for 7 seconds. This will reboot the IPad.
Connect to your Wi-Fi
Princeton IT suggested as a work around to turn these notifications off.
Workaround for "iOS 4.1 - 4.3.3 Allows DHCP Lease to Expire, Keeps Using IP Address" Bug
Use a fixed IP address
Settings/WiFi/click on the arrow of your Wi-Fi connection/Static/
Fill in the IP-address, subnet, routers IP and DNS
Some mentioned that using Google’s’ DNS worked for them
Type this in the DNS field: 18.104.22.168, 22.214.171.124
Magnets and electronics do not like each other. It could be that the smart covers are creating some sort of interference. I modified an Ipad case, by adding a small magnet and I do have the feeling (no real proof) that the Ipad disconnects less often without the case. (It still disconnects though.)
The following suggestions require some basic knowledge of your router. I suggest that before you do any of the suggested changes you make a backup of your routers configuration first. That way you can easily restore your old settings.
Since there are many routers available, with each his own layout I will not go into the details. Read the manual of your router to see where you can apply these changes.
Some users have replaced there older router with a new model and this soved their problem.
Modern routers have dual band (2.4 and 5 GHz). Try using a single band
Also some routers have a dual range of 20 and 40 Hz. Try switching to 20Hz only
QoS (Quality of Service)
I believe on some routers this is called WMM as well
Some users say switch it on, some say switch it off. I tried both without success
Switch from WEP to WPA2
Today I read on Apple support the suggestion to turn security off and use MAC address access. I have not tried this yet, but will do this tonight.
Some suggested to reset the network settings on your Ipad (see above) and switch off the router for 60 seconds as well.
If I find other possibilities I will add them here.
