Life after Vista SP1

I Installed Window’s Vista SP1 on my Dell Inspiron 1520 with Vista Home Premium and the installation was without any issue though it took the better part of my morning for almost a 75 minutes. Thankfully I haven’t experienced any serious problems like BSoD or the computer hanging as has been reported by many who installed it. Though I haven’t been able to see any noticeable changes as yet.
I have had one small problem though…. I keep getting disconnected from my household wireless network. I know for a fact this is not a problem with my router or internet connection as the other computer’s at home do not get disconnected. Any idea’s what the problem could be? ?

I have not yet re installed the driver’s and also yet to report the problem to Dell customer support.

So if you do have an idea of what the problem could be do leave back a reply.
