Well it has been 3 days since I installed the Linksys N router, and it has been working perfectly, I havent had to reset it once, and I have been doing nothing different then usual streaming some netflix, hulu, gaming, uploading files, browsing the web etc.
No dropped connections, no IP issues, both my iPhone and my wifes iPhone have not lost connection to the WiFi once since we got this new router.
This linksys is in G/N mode using the same WPA key as previous dLink router, I configured it as close to the dlink as their options would allow. I also mounted it in the exact same spot, ran power from the same outlet etc.
Also speed tests with my dlink were always 20 - 30Mb, with my linksys I have been during 36 - 40Mb constantly, so there is also a speed difference between the units.
I can only conclude that D-Link has not yet learned how to make a working wireless router. I also never had faith in Linksys products, but this one sure has my vote so far. Will keep everyone updated.
