Hi all -- I'm having problems with my wireless connection on a Notebook Inspiron 1545 running Windows 7.

If I use a wired connection -- all is well -- but with Wireless -- I am able to connect to the Internet -- some programs connect -- others do not.

Examples -- AOL Instant Messenger Connects.  Most web sites under Google Chrome / or IE do NOT connect -- but some do... one that comes up is Google Mail.  A couple that do not come up -- cbs.sportsline OR usatoday.com -- note -- as stated above -- if I attach an ethernet cable the pages come up as expected..

Any ideas what could cause the wired access to act so flakey ?

Some Notes --

• Other computers are running ok on this connection point (cable modem - router from Netgear).
• I did try disabling the Firewall (McAfee), but behavior was the same. 
• This problem has presented itself in the past and then things seems to start working -- problem is intermittent in nature.

Thanks in Advance -- HisRocker.
