So, if I replace the card, I can get at least 30/30 with an N router? Thanks.
Yes. it's best to replace the 1397 (You should keep the card around or sell it to someone who will use it. Don't toss it away!) with a card, such as this one: http://www.intel.com/products/wireless/adapters/6200/index.htm
That one is in fact a Dual Band card, in case you're wondering. It runs for no more than $30 online and it should be compatible with any system having a Dell 1397 wireless card in it. If you're wondering how it changes out, at the bottom of most laptops there is a door covering up the Wireless card. As long as you can open that door, remove the two delicate antenna connectors, unlock the old card, put the new card in the slot, lock it, connect both antennas, and put the cover back on the laptop, you should be good to go. I would never use a USB Wireless card on a laptop since the cards are easy to replace and all laptops have a dedicated PCI Express Bus just for Wireless, which is loads faster and has far less overhead over other methods.
As a tip: Most laptops put the Wireless card in the same location or somewhere near the RAM!
