can I use a laptop to set up a wifi access point?

When I first received a laptop of opportunity in last December, a colleague tech at my night school mentioned that I didn't have to buy a 803,11 access point device to plug my switch, but I rather use a WiFi card on my computer to create my own access point. I told him I have such a card and put a little out of my mind.

However, I have someone outside to spend the night at my place, and he needs to check his e-mail. Unfortunately, it seems that the RJ-45 socket on his laptop is broken, I have tried several cables and impossible to get a connection, including the cable to connect the computer I'm using now.

Is it possible that I can use ICS on XP Pro (preferred) or Vista 32 bit Home Premium (really want to use it, I have never set the boot loader after the upgrade to XP on a separate partition, especially because XP has worked so much better) to set up enough connectivity for him to connect to the mail server?

Should I Windows 7 or Vista to do this? I know how to do the reverse quite easily (share Wi-Fi on the Ethernet port), but I don't know how to set up the SSID and others. I would assume same WEP or WPA2 (Yes, I know how it is easy to crack, but it's better that transmitting passwords in clear text because it discourages occasional interception) would too, so it will accept a connection open, unencrypted. I'll just close access once it does.

How could I go to set it up? I'm not spending money on software that is not free for one night, one-shot deal. Kiss, I just need a connection of bare bones for him. If its Ethernet port was working, I would leave him to plug my switch, but since it's not I need to create a gateway using what material I have on hand, and the only device with any kind of ability 803.11 is my own laptop.

I know it's possible, I don't know if this is something only Linux, or a solution that requires 3rd party software.

Yes, you can use ICS.  See http://practicallynetworked.com/sharing/xp_ics/

I forgot to include this--> http://www.home-network-help.com/ad-hoc-wireless-network.html

You will need to configure security manually from the properties of maps dialog box wireless (on both computers) and IIRC, you can use WEP in ad-hoc XP networks.

Go to the correct place
Right click on the wireless adapter icon and select Properties
Click the wireless networks tab
Click Add to create a configuration
in the 'Association' tab, set the SSID, network authentication 'Open' and WEP data encryption.
It's been so long that I made that I remember exactly, but I think you can use only the 10 digit Hex key.

  • Can I use my WRT160N V1 as a signal booster/access point?

    I have a router Linksys WRT160N I want to use it as an access point for the devices in my basement. The main modem is a century link PK5001A. How could I go to set it up?

    Yes cascade would be wired AP.

    If you mean you want to change the WRT in a wireless Repeater that is different. In this case, you are lucky DD - WRT is compatible with V1.

    http://www.DD-WRT.com/site/support/router-database

    Change the firmware for this 3rd part and configure the WRT as wireless Repeater. It is not easy to config but there is a lot of documentation for DD - WRT.

  • Can I use my laptop as a media extender?

    I want to be able to launch Windows Media Center on the laptop, I it would launch on XBOX for example in the same way. And then use the same way I would use it on XBOX.

  • Can I use another laptop with Satellite L550-129 adaptor?

    Hello

    My Satellite L550-129 card is broken. (dc 19 V ~4.7 (A).

    Can I use an adapter of a mini laptop Toshiba NB500-135? (dc 19 V ~ 1.58 A)

    It is therefore the same Volt but a lower amp, can I damage something?

    Greetings,

    Bart

    Hello

    Volt value must be the same! It is very important to avoid than anything.
    In your case, the same value of Volt AC to other support adapter, so you won't damage anything other THAN the value of the intensity is very low and I guess that the adapter does not provide enough power for L550 notebook. For example: recharge the battery would take much more time.

    However, I think you could check it simply as mentioned; you won't damage anything.

  • Can I use the laptop without the battery?

    Hello

    The other day, I bought my first laptop. A 17 '' HP Pavilion running Windows 7. My question is can I remove the battery and just run through the power cable? I heard that you can with some laptops, but not with others.

    I have take the laptop with me places that I will use it as a PC of office most of the time. I guess that charge and discharge the battery in time, will be so if I need to use it on the road I might as well give the battery a rest.

    Many people now use a laptop in the same way as a desktop computer, at work or at home. As the laptop is plugged in and rarely/never moved or disconnected or completely stop, simply allowing it to enter the mode "shall". Such use does not seem to contribute to battery decline we see here a lot of messages. HP & other manufacturers do not recommend removing the battery in such a case. Since I unplug/move mine sometimes I keep the battery in and don't forget to unplug and leave it to unload and reload periodically. This has worked well for me.

  • Can I use my laptop CD drive good install disks of program on another mini laptop (with broken screen)?

    I have a Dell Inspiron Mini running on Windows XP, that I dropped and broke a plastic wedge.  The broken plastic cut a wire to the screen, leaving me with a white screen.  I was able to use the fn 1 toggle to turn on a second monitor via a HDMI cable.  However, I decided that the blank white screen bothers my eyes, I went into the display settings and select 'make this my main screen' which means, do my main screen TV.  However, he turned off the TV screen instead of the empty white laptop screen.  The Fn 1 button no longer works.  I tried to do a manual telephone walkthough with Dell system restore.  By restoring the computer to its factory settings, I should allowed to use the Fn 1 button again to turn on my TV via HDMI cable - without success.  Therefore, Dell confirmed that I had a software internal problem and recommended that I post him for repair (no guarantee).  The Dell Inspiron Mini has no CD Rom internal drive, however, I have the original disks supplied with the notebook software program which is five years (or more).  The Dell Inspiron Mini operating system is Windows XP.

    Now, I have a laptop HP large format, with CD Rom drive, running on Windows 7.   Can I use my HP CD Rom to install the original records of the original Dell Inspiron mini Dell program?  Thank you.

    Thanks for the tips.

    You are welcome. :)

    No, not in the way you're probably thinking.  The video ports on the MBP are outputs - video input , you should use a VGA/DVI to Firewire/Thunderbolt adapter (you don't mention which ports you have decided to use or machines) and software to display it in a window.

  • setting up wrt150N as access point

    Hello.. Please bare with me.
    In my previous House, I had my cable modem connected to a dlink wireless router. I used a port on the dlink lan and connected to my wrt150n that is configured as an access point. It has worked flawlessly. I was able to create a network and share files between computers regardless of what router they were physically connected to.

    Fast forward a year and in my new House, I have a dlink WIRED router connected to my modem (different ISP) and to a lan port on the router im connected to the port of the wrt150n 'internet '. The computer is connected to the 150n can access the internet and the portion wireless works fine, but it does not connect to another computer that is connected directly to the router wired dlink.

    From the computer connected to the linksys, I can;

    router dlink ping

    router linksys ping

    ping ip address ONLY, the second computer that is connected to the dlink router

    The computer connected to the dlink, I can;

    router dlink ping

    I can not ping ip address AND name of the other computer

    I cannot ping the router linksys

    Is happening here?

    What setting should I watch these two computers to be on the same home network?

    Dlink ip address is 192.168.0.1

    Address IP Linksys is 192.168.1.1

    He was installing it in my old House and worked well.

    Unfortunately, my warranty is up and linksys don't offer me a tech support.

    any help would be GREATLY appreciated, I really need my home network courses.

    It's just the way you have implemented: you configured the WRT as router and so you have created two separate LAN segments and areas of broadcasting. Emissions of LAN will not cross a router. Name resolution for the WIndows work group works on the basis of emissions, either it works on the same segment of LAN never beyond a router. For example, if you want to keep this type of installation, you will need to use the IP address to connect to computers on the Dlink from computers on the WRT. Reverse is not possible at all because the WRT does NAT which makes LAN inaccessible on the internet port.

    You want only the WRT as access point and you seem to want connectivity complete between all your computers I would say that you reconfigure the WRT.

    1. disconnect the WRT from D-Link.

    2. connect a computer to the WRT. Open the web interface at http://192.168.1.1/

    3. on the main configuration page, change the address LAN IP of 192.168.1.1 to 192.168.0.2 and disable the DHCP server.

    4. save the settings. You will lose the connection.

    5. unplug the computer and wire to one of the LAN ports of the WRT to your D-Link router.

    That's all. Now all your computers to connect to the same local network and are in the same broadcast domain. All computers use IP addresses * 192.168.0 and have internet through D-Link.

    Make sure that the DHCP server on the D-Link will not affect 192.168.0.2 to another computer or device on your network. This would cause a conflict of IP address.
