Seems like this is a possible Galaxy issue. Specially if you get to internet sites with other PCs and devices.
Does the galaxy connect to other routers, say if you went to a friends or families place? Does it work there on there WiFi?
Well I see there isn't any v1.02 on the DLink
NL web site however the
tsd.dlink.com.tw has a WW version:
Firmware:DIR-645_A1_FW: v1.02b08 (for WW)You could try that and see.
If you decide to try it, please follow the
FW Update Process. I would Update and don't even set up the SSID or PW, leave it off, just get the router connected to your ISP Modem, check internet connection with a PC, then if your good, try to connect the Galaxy to the default SSID of dlink and it shouldn't have a password. Will the Galaxy connect and get to internet sites then?
If after this the galaxy fails to connect to internet sites, I would phone your local regional DLink support office, level 2 if you can and see if there is any help.
I would go to the store that has a good refund policy and buy a different router just to test and see if the galaxy does the same thing or not. Then return the other router after the test.
