    Yes or no. if not why not exactly ? I simply want to share the interent with
    a laptop via a wireless router. What is the easiest and cheapest wireless
    router out there ? So far I find the whole setup procedure very complex. Is
    there a good simple to understand how to guide out there for simpletons like
    me ?!

    Hi Dave,

    the absolute cheapest way of doing that is just to have a wireless card in
    the PC and a wireless card in the laptop. Then connect them in adhoc mode.
    Windows own wireless networking software should do a good enough job of
    automatically detecting the setup. Just make sure that your firewall (if you
    have one) supports internet connection sharing.
    Adhoc limits you to just the two machines as only two machines can be
    connected in this mode at any one time. If you decide to expand to more
    machines, then you will have to get an ADSL router.

    Hope this helps

  3. if the computer has an ethernet card then you should be able to share
    the connection by wiring a wireless access point to the pc's network
    card with a crossover cable. If not a cheap 4 port hub will fill the
    gap - I used this before getting an adsl router.

    you don't even need a router. ADSL pci modem + pci 54g + pcmcia 54g.

    HI MIke, yes it does. I know PCI wireless cards exist (I have a pcmcia
    version for the laptop) so ad-hoc mode seems the solution not sure why I
    need a router then, any advantage in having one ?

    In your case, Dave you don't need a router, as I say, if there are only ever
    going to be two machines connected at any one time. A router would become
    necessary if you wanted to add another device to the network, i.e. another
    PC or a network printer. If that was the case, then you would be better off
    getting an external, ethernet ADSL modem, attached to a wireless router,
    then all the network devices would be able to use the internet or the
    printer at any time. At the moment, the laptop can only access the internet
    and printer if your main PC is switched on.
    Go they have a configurator section. Very informative.

    A router for ADSL usually means a router \ modem - i.e the router has the
    modem built in as well as a switch (either Cat5\RJ45 style wired or wireless
    or both). This means that you plug all your machines into the router on the
    LAN side using normal network cards (often built in these days) and connect
    the adsl service on the WAN side of things - so the router well routes lan
    traffic to the internet and looks after the connection in a much more secure
    and stable way for you.

    So.... your left with a redundant ADSL card which is pointless. What you
    could do though is get a wireless access point, entirely seperate device -
    it is NOT a router, connect this up (again you can plug the main pc in using
    a cable if you wish) and add wireless cards to the PC's, basically an access
    point is a wireless hub\switch.

    Using just an access point would mean that you would need to use something
    like ICS (INternet Connection Sharing) built into windows to share the
    internet connection with the other computers, the access point then just
    networks the pc's together and allows them to pass data around - it doesn't
    directly manage anything to do with the ADSL connection, the PC in effect
    acts as a router to the rest of the machines on the network.

    Problem is that you need to leave the pc on all the time anyway and many
    people may choose to go for an all in one ethernet 4 port swtich, wireless
    access point and adsl router - just plug it in and it looks after everything
    without any specific computer having to be left on - this is my personal
    prefered soloution and it does solve alot of security issues and stops the
    other people on the network using adsl slowing down your machine because
    they are using your workstations resources.

    As for setup, it isn't *that* complex, you it will basically work out of the
    box, with things like usernames and passwords being put in and security
    setup needed, through a web based interface. Whilst I wouldn't recommend a
    complete novice do it, anyone with a reasonable understanding of computers
    and how a network is actually working (that it is based on IP addresses,
    that the computers on the lan all have one internal ip address and the
    router has both internal and external etc) could do it. It is difficult to
    mess it up but some idea is useful to make sure you can wire it properly.

    Good news is that once its done its done with a router, it will just work
    without you needing to worry about how ever again (well in theory anyway). I
    could setup adsl and a few workstations to get net access from a router
    within half an hour easily, nothing complicated about it, just the
    confidance to install a few wireless cards and enter some details to ensure
    everything can talk to each other.

    Having just done what this message suggested, I endorse everything it

    Worked out of the box. Very easy. Much more convenient than ICS, which
    can be a pig to troubleshoot.

    Thanks for going to the trouble of explaining but my head is still spinning,
    not sure I'll ever get there

    OK so from a laptop or PDA (with wireless card) I can connect to the
    desktop's ADSL connection with just a wirleess PCI card as long as I'm
    online on the main pc of course yes ?

    Although I use an NTL set top box/cable modem connection, When I was
    extending my system to include wireless networking, I went to the Linksys
    website and clicked on the "educate me" tab. This gives a
    very clear, pictorial, explanation of what goes where and when for home
    networking, hardwired and wireless. Admittedly it is in terms of their kit,
    but I found it very useful.

    As far as an ADSL equivalent, Belkin have a neat, one-piece, ADSL
    Modem/Wireless router with 4-ports of Ethernet. Not the cheapest kit, but I
    installed one from scratch for a mate of mine in less than an hour. They
    also have non-wireless kit as well.

    All manufacturers worth their salt have downloadable manuals for their kit,
    so it is easy to get hold of these to read, hopefully understand and use to
    decide which is best for you.
