no
Yes a broadcom wireless card
My fiance owns a Dell Inspiron 1110 and it does have built in wireless. All newer laptops beyond a certain year have built in wireless.
Yes it has a wireless card built in.
No, there wasn't a Dell Inspiron 1390. The is a Dell 1390 Mini Card 802.11 b/g, which is a wireless card.
No. The Dell Inspiron 1100 lacks a MiniPCI or MiniPCI Express slot in which to connect a wireless card internally. However, it does have a PC Card slot, into which a wireless card could be installed, with only some sight protrusion out the side.
The Dell Inspiron 1100 does not have a built in wireless adapter. You would need to add one by USB or PC Card if you wanted a wireless router. For a wired router, any 10/100 router connected by a CAT5 cable would do, which is almost universal compatibility.
No they can not they are solder into the motherboard while built
The Gateway 7330GZ Notebook has a built in Gemtek 802.11g Wireless Card.
yes
You need to get a wireless card, connect to your computer and have fun.
No, unless that wireless card is a bluetooth adapter some computers will have it built in but if you don't know it doesn't.
If you cannot see where a mini PCI card will plug in and Dell will not mention how to connect the card then you may need to get a USB wireless 'dongle' instead
