Dell c 800 laptop has internal wireless card. Worked fine until recently when it lost contact in any room except where the wireless router is. Other computers in the house are working normally with the router. Is the internal card going bad?

That is a possibility, however, try cleaning the contacts where the two leads are for the wireless antenna hooks to the card and reconnect them. It could be that they are dirty or have worked loose. If that has no effect, then take the machine somewhere that has free wifi and see what kind of range you're getting by seeing how far you can get from the place with the card still seeing the network. This will tell you if it's the card or your wireless router at home, these go out too. Keep in mind that most McDonald's, Hardee's, or Wendy's with wifi have barrier film on their windows to force people to come inside to use their network, hoping you'll purchase something. Most motels with wifi do not have this barrier film and keep their routers on the roof or central location. You don't have to be actually connected to the internet, if the card sees the network, then it's working properly.

There could be some sort of interference going on.

There are two ways that you can fix the problem:

1) See if your wireless router can support a bigger antenna. Linksys has that feature for their routers.

2) Disable your wireless adaptor and go with a USB wireless adaptor or better yet a PCMCIA adaptor if your computer has one. That will increase reception since these devices have an antenna like shape to them.

Dell V510 printer worked fine wirelessly until we got a new Belkin Router


The printer's IP address most likely needs to be changed.
Check the Belkin's IP address range (it maybe 192.168.2.***) and configure the printer's IP address accordingly.

Dell Latitude D 410 has suddenly (worked yesterday) stopped connecting to all known (and working) wireless networks. Is my internal wireless card gone?


If you get a 'Limited connectivity" on you wirelessconnection on your laptop, it means that the wireless card on your laptopprobably did not get an IP address from the wireless router.
To fix this problem, right click on the wireless icon on the Task bar and thenclick Repair.
This will force the wireless router to issue a IP address to the wireless cardon the laptop.

Cant find where to install a wireless card internally to my dell inspiron 2600


You can't install any cards internally as there isn't any room inside. If you want to add wireless capability you'll need a USB wireless adapter which you just plug in to one of the USB ports. This computer also has PCMCIA (card-bus) slots, but that's older technology. USB adapters are much easier to find.

Cannot print from laptop to printer using wireless print server


This is probably the Software Firewall on your laptop

you should probably tell your firewall software that you have an internal network (Laptop-desktop-printer) you should add the IP range of the wireless network as a trusted network.

Internal Wireless card get really bad signal


The particular wireless card that comes stock in those laptops is horrible. I work for a school district and we have 10 of those laptops in a school library with a wireless access point. They constantly lose connection, don't get an IP address and generally don't work well at all. We have tested everything we can and have narrowed it down to the fact that that particular wireless card is a piece of junk. We are currently outfitting all of those laptops with new PCMCIA Wireless cards. We tested a single laptop using a new card in the slot and disabled the internal wireless. After that was done, the laptop worked like a charm. For a comparison, we have other laptops in that same library that have an Intel wireless card instead of the Dell one. They have always connected fine and with no issue to the same Wireless Access Point that the Dell wireless has problems with.

Range is very poor


You need to change the wireless channel of the router. Access the router's setup page through http://192.168.1.1, no username, password is admin. Go to wireless tab, Select Manual Setup, change the Radio band from auto to Wide Range. Also change the Wireless network name to a different name then click on save settings at the bottom. Power cycle the router, unplug it for about 30 sec then plug it back in.
