I own a refurbished Dell Latitude D620 laptop that was sent to me by Dell last year. Currently, I am unable to connect my D620 to my family's wireless internet network (I am home from college). But I AM able to connect to my NEIGHBOR'S wireless network AND my Dad's Dell Inspiron 6000 works fine on OUR wireless network.

I first received this D620 last summer when I was also at home from college. During that time, my computer was able to connect via LAN cable. When I went back to school, I ONLY used wireless. When I came back home for winter break, I was strangely unable to re-connect to my house's LAN cable and my ethernet ports did not light up. Furthermore, I was unable to make a LAN cable connection to OTHER routers and modems as well.

I want to connect to my house's wireless network, but I can only get an INTERMITTENT connection. Meaning, I can load gmail.com but not log into my account, or I can do a google search but not connect to the links produced in the results. EVEN AFTER reinstalling Windows XP. Again, my D620 works fully on my neighbor's wireless network BUT intermittently on my OWN network, but my Dad's Inspiron works fully on OUR wireless network and router.

I thought I would need to replace my motherboard since my ethernet ports seemed broken. HOWEVER, now they are working again! BUT I'm not sure exactly why! 2 possibilities:

1) there is a power conservation mechanism on my Dell D620 that deactivates the network card when you unplug the power. I have read that this mechanism can actually really interfere with LAN line connections (and not wireless). So I deactivated that power conservation mechanism.

2) i installed a new hard drive and reinstalled Windows XP. perhaps this cleared out residual software that was interfering with my LAN line connection?

My family uses a ~3 year old Netgear MR814v2 router. I am told it is 802.11v and only capable of 11 mbps, whereas newer 802.11b models are capable of 54 mbps. I have talked to netgear about proper configuration settings -- e.g. setting it to the right channel (11).

Do I need a newer router? But why does my Inspiron work fine but the D620 alone has intermittent wireless connection. Or are there possible problems with my D620 I have not considered?
