Hello buckeye044 Since there was internal work done on your system there exists the possibilty that either the card is not fully seated into the system or the antenna was not reconnected. So Look HERE <ADMIN NOTE: Broken link has been removed from this post by Dell> on how to access the mini PCI card to check if it is hooked up. Won't hurt to reseat the card also.
Inspiron B130 Just had my DC Jack and fan replaced and now my 1370 WLAN mini-pci card is not picking up my wireless router.  I know it isn't a router problem because my wife's laptop functions fine.  Troubleshooting tells me it is working fine.   I get very poor connection when right next to the router but lose it at 10 feet. Please help.
