Sony Ericsson Xperia X10 :: Losing Wi-Fi Connection

Is anyone else having trouble staying connected to "Wi-Fi"? I am having 3 problems:

#1: For some reason, my phone will show the connection and 10-15 minutes later, the connection is gone. Nothing changed, the router is like 2-4 feet away and it is a "G" router.

#2: The other problem I am having with the Wi-Fi is the indicator will drop off of the notification bar, but when I go to the settings, the Wi-Fi is highlighted like it is connected, but there is NO connection stated under the Wi-Fi setting.

#3: The Wi-Fi will drop off of the notification bar and when I go to the settings the Wi-Fi indicator is highlighted indicating active, but again, nothing under the Wi-Fi stating what the connection is. So I choose the same connection it has been using and I connection will state it is out of range, when in fact it is 2-4 feet away, again, nothing changed. So I reset the router and it will try to obtain a connection, but says it is unsuccessful, however, the network states under the name that it is "Remembered". So I highlight the network and than I get a Disconnect. This is really becoming an irratating issue! It worked fine first 2 days and than bam, starts to go crazy. So is anyone else experiencing this issue?
