I have a dlink DIR-615 attached remotely to another home router system. It is hardwired via a LAN port and I connect to internet via the remote DLINK router via wire or wireless just fine. Problem is I can't access the DLINK router programing. I have reset it a few times and reprogrammed but once I exit I cannot access the IP address I gave it when programming. Windows shows no website found

Try to upgrade the routers firmware.

Do you have the Internet connected to the Internet port in the back of the DLINK? You will have to configure the DLINK for internet access. Open a web browser to your DLINK and check on the configuration under internet-setup. Select the type of internet connection you have i.e. DHCP, PPPoE, Static, etc. Once that is set up, you should have access to the internet like before.

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 ?

It appears your brother has changed your wireless router settings.
You can reset the Dlink back to the default settings by -
Power off the Dlink and press and hold the RESET button on the back of the Dlink and the power on the Dlink. Hold the RESET button for 5 secs. until the LEDs flash at the same time.
Connect a LAN cable from the computer to the Dlink. Open a browser and enter the Dlink's configuration URL
http://192.168.0.1
Default login = admin
PW = blank (just press Enter)
You can now change the admin password and set up a new passphrase (ie encryption)
