Why not just get a regular everyday 30$ router and separate your wireless SSID's between your parents house and your house ?
Here's the scenario.
I have the speedtouch DSL modem, connected to the D-link wireless router, which provides wifi coverage.
Both of them+ PS3 connected to UPS.
UPS is in my room, cause the PS3 is there.
And i want the modem and Router in my room, so that i'd connect them to the UPS ( i really don't want to buy another UPS )
If i do that , it covers my whole apartment but not my parent's.
If i put the router in the living room , my parents get the minimal coverage .
And there's nothing but one wall separating the 2 houses.
I thought of getting the edimax ew7209 Access point, use it as a repeater ( to cover my parent's house ) and Question is will that cover it if i put it in the living room ?
Does it have more coverage than my D-link ?
Edit : nevermind i'm getting the Access point, i'll find a way to get coverage there with it
Thanks guys !
