very important to make sure you have good signal strength... and no, looking at what the PC and or MAC show for their wifi signal strength is a far cry from the truth...
When connecting to the GS-911wifi hotspot (D2D), make sure you are close, and also check that you are not shielding the device with any metal...
When using infrastructure, i.e. connecting to your home network, signal has to be strong... if signal strength is not a problem, then you might have other network issues...
Let us know what router/AP you are using..
on your router/AP, go into the settings and disable the Short GI and WMM - there are many references on the net where these are creating havoc, and we found the same on some routers/APs...
some other tests you can do:
Pinging your GS-911wifi interface from your PC
1. find out what your GS-911wifi's IP address is (the utilities are great for that).
2. on windows, open a command prompt and ping your GS-911wifi - let's assume your IP was 192.168.1.101, then you would type:
ping -n 25 192.168.1.101
where the "-n 25" instructs it to send 25 ping requests to the supplied IP (4 is just not a good statistical number)
Pinging your PC form your GS-911wifi device
1. make sure your GS-911wifi is connected using the USB cable
2. find your PC's IP address (in the command prompt type ipconfig)
3. open the GS-911wifi utility
4. select wifi tests and enter your PC's IP address... this will have the GS-911wifi ping your PC
If you're looking for a cheap AP/router that works, I recommend the TPlink TL-WR702N... Wallmart and Newegg sell them for less than $20.. These are great little router/AP combos, that we've had no issues with.
