Wifi when i log onto the internet via wireless conection it works at first. However shortly after i get a message saying no gateway. I am then no longer able to get connected unless i reset my phone the same problem then happens again.In short i am unable to connect to the internet via wireless connection

make shure that the wifi you are conecting to,isnt just a wireless router thats turned on..lol..like not hooked to the internet

Have you set the TP Link TL-WA901ND IP to have 192.168.1.1 as the default gateway ?
Also DHCP server is where ?
IN the TP LINK TL-WA901ND or in DLINK DIR 615
Only have one Router running DHCP and set the default gateway in the leases as 192.168.1.1.
What subnet mask are you using is it the same through out all devices ?

When was the last time you could connect to the internet via wifi? You could do a System Restore back to that time.
And/or, connect to the internet via an ethernet cable and update the BIOS on your computer.
And, make sure you can find your current wireless driver on the internet; delete the wireless driver, from your computer (it might be corrupt), while in safe mode. Then restart and download the current wireless driver in normal mode.

go to start run and type cmd and press entere. A black screen shows up. type ipconfig then press enter. You may have to scroll up but the number next to gateway is the ip address you need to type into your browser to get acess into the router.

You should check the password which you have given for the router. Either you are typing it wrongly or you have forgotten the correct password. Try resetting your password and then try to connect your laptop via that router. Your problem will get solved

I am having exactly the same problem. It occurred on Sunday 17th. I have phoned Optus who seem unable to work out what has happened. It will work wirelessly but not recognise it when set up via ethernet cable.

1st you try to ping the the wireless device ip address if you getting the replay that means your wifi is working fine .check the usb cable also for testing directly install on your pc and check it.

You need to set up a new log in code

log in to your router and check settings there

Log onto the router to see if the entire box is hanging or only the conection to the internet.

Check for a 'Auto Reconnect Setting" in the router.

If there is alot of Noise on your DSL lines it could disconnect without re-connecting.

Also check to make sure you have all your filters installe don the phone lines....
