I have an Acer Android Iconia Tablet A500 and it kept dropping the WiFi. I wiped, reloaded it, applied the patch and nothing would fix it.
I was about to sent it in for repair. Then I noticed my HTC EVO 4G was doing the same thing!
Like many people it "seemed" like my Windows laptop did not have the issue. Really Windows handled it better and reconnected. Android would drop the the connection and disable it!
Solution: After some research the issue was that a new neighbor moved in and they had two routers both on channel 1. Guest what? My router was on channel 1. This caused some the Android O/S to get "confused" and it tried to connect to the neighbor's router and could not and the connect dropped.
Download inSSIDer and check out the channels your neighbors are using. Then go into your router and pick one that is not being used, or you can barely pick up from the other people living around you. You can also download a WiFi app for Android, but it is better to use the one for Windows if you can since it will keep the connection.
You can hit the error "Maximum request length exceeded" if you are attempting to upload large files with ASP.NET
The web.config setting below changes the max size to 100MB
<httpRuntime requestValidationMode="2.0" executionTimeout="240" maxRequestLength="102400"/>
If you have used ASP.NET to upload documents into a database and got the error "There was an error opening this document. The file is damaged and could not be opened."
If you are using a DataSet and TableAdapter check the parameter on the stored procedure (if you used a stored proc) the size probably defaulted to 65336. Change it to -1 and you will be all set.
After (type is -1 and tab to the next field)
