STILL cannot connect to visible wireless

[rsjabba]

Gday.
I posted with this exact same problem in early 2009 - nothing of my hardware or config has changed since then, but I thought I'd ask again to see if any solutions have come up since.

So, I have an Acer TravelMate 5740G (all other system specs are fine so i'm only posting the networking relevant stuff) and it does not connect to wireless networks
- Acer Nplify 802.11bgn
from a broadcom 802.11n wireless adapter
apparently has the best driver (as advised by MS device manager)

this pc has been able to connect to a grand total of 2 wireless networks
1. at uni it connected on its own for 15 minutes, any time i've attempted to manually connect it says "could not connect to [network name]"
2. connected just fine to a 3g iphone 4 acting as a portable hotspot

at home, my wireless settings are as follows:
Open WEP PSK w/ 1 key index
everybody else in my family can connect to this wireless network
i can connect with my phone, my dad with his lappy, my friends with their lappies.
there are NO xp computers in the network
there are 3 w7 desktops on the network
the internet works just fine with the rj45 cable
---> i'm 100% sure the issue is not with my home network config OR the router

at uni, the router + settings are not the issue because they service 15,000 people a day without issue
---> i'm 100% sure the issue is not with other network configs OR their routers

i have tried every change under the sun (that i know of) with my laptop's own configs.
i've attempted to update all the WNIC drivers, i've made the WNIC as open to connections as i possibly can.
i have disabled ip6 and tried, i have enabled ip6 and tried, and i get no connections happening.
i'm at the end of my wits, i just want my wireless to work, and i have NFI how to make it happen.
Can anybody please help me?
