To everyone having this issue, i think i may have solved it.

Please keep in mind that every router is different so i cant give you specific instructions, but ill do my best to make the instructions clear.


Heres what i did:

step 1: open your router's web interface on your PC (consult with the router's user manual to find out how this is done)

step 2: enable "advanced settings" mode, and enter the configuration page

step 3: navigate to your WLAN settings page

step 4: change your wifi security to WPA-PSK

step 5: Look for a setting, or menu called "DHCP server" or something similar. sometimes a sub-menu under "LAN"

step 6: Disable the DHCP server. (please note that by disabling this setting, your router will no longer assign your N9, or any other wireless device, with an IP address....you will have to change the settings on your N9 and give it a static IP. you will need to know your network's settings for this)

step 7: save settings on router and restart.

Step 8: enjoy a problem-free wifi connection!

:-D

please let me know if you need any assistance. ill do my best to try and help
