Hi if you have an unsecured connection, i will recommend to use a secure connection with any password protocol. it will ensure your connection. if you already are using one, try a different secure option. one thats compatible with both the laptop and hub

How do i replace ide/eide cable on my dell latitude c840


Buy a replacement and fit it I guess. Why would you need to replace an item that doesn't fail?
As far as I am aware there is an adapter; http://www.ebay.co.uk/itm/HDD-Hard-Disk-Drive-Caddy-IDE-Adapter-Connector-DELL-LATITUDE-C800-C810-C840-/380698290269?pt=Laptop_Adapters_Chargers&hash=item58a362e85d and maybe a flexible cable; but that is for the screen.

Tip

Set up a computer-to-computer (ad hoc) network


An ad hoc network is a temporary connection between computers and devices used for a specific purpose, such as sharing documents during a meeting or playing multiple-player computer games. You can also temporarily share an Internet connection with other people on your ad hoc network, so those people don’t have to set up their own Internet connections. Ad hoc networks can only be wireless, so you must have a wireless network adapter installed in your computer to set up or join an ad hoc network.

Click to open Connect to a Network.

Click Set up a connection or network.

Click Set up an ad hoc (computer-to-computer) network, click Next, and then follow the steps in the wizard.

Notes
If one or more of the networked computers is joined to a domain, you need to have a user account on that computer to see and access shared items on it.

If the networked computers are not joined to a domain, but you want to require people to have a user account on your computer for access to shared items, turn on password protected sharing in Network and Sharing Center.

To turn on password protected sharing
Click to open Network and Sharing Center.

Under Sharing and Discovery, if password protected sharing is off, click the arrow button to expand the section, click Turn on password protected sharing, and then click Apply. If you are prompted for an administrator password or confirmation, type the password or provide confirmation.

An ad hoc network is automatically deleted after all users disconnect from the network or when the person who set up the network disconnects and goes out of range of the other users of the network, unless you choose to make it a permanent network when you create it.

If you share your Internet connection, Internet connection sharing (ICS) will be disabled if you disconnect from the ad hoc network, you create a new ad hoc network without disconnecting from the old ad hoc network for which you enabled ICS, or you log off and then log back on (without disconnecting from the ad hoc network).

If you set up an ad hoc network and share your Internet connection, and then someone logs on to the same computer by using Fast User Switching, the Internet connection will still be shared, even if you didn't intend to share it with that person.

I hope you all found this information useful and helpful.

Why does connecting to an ad-hoc network disconnect the shared mobile broadband connection?


You can be connected to two signals at one time, if I understand your statement. My question is, why is your laptop automatically connecting to a Ad-Hoc network? Your wireless adapter Intel Wireless 3945A/B/G,settings should be scrutinized. Perhaps this will help:http://www.intel.com/p/en_US/support/highlights/wireless/pro3945abg

Compaq n6120 - can't connect wireless


Most wireless networks are setup as infrastructure networks, meaning all communication is to/from a wireless access point/router that serves the same function as a switch/hub in a wired network as a central point to transfer communications from machine to machine. One works over the air the other through a wire.

There is an alternate form of wireless networking refered to as ad hoc -- in this version of wireless networking every wireless adapter can "talk" to any other wireless adapter configured with the same SSID (name) and security encryption (none, WEP, WPA). This is how somewhat less impromptu wireless networks are created similar to impromptu infrared networks some of us have used. One limitation of the ad hoc networks I have seen configured to date is access to the internet. I have posted an article where a stationary PC (required to be running for any other wireless machine to access the internet) with a wireless card in ad hoc mode could act as the router for wireless network but it required a cabled connection the internet. I suppose it could be a second wireless connection on a separate channel with a second wireless adapter in an infrastructure network but why? These types of networks are only recommended in another article for a limited (small) number of machines.

Based on this are you asking to create an ad hoc network to connect 2 PC's wirelessly without a wireless router or access to the internet from the wireless network (without a dedicated machine)?
