Network Problem?

  1. Hi basically, I installed my wireless broadband on my desktop PC it is connected to the PC using a Ethernet cable. Internet works fine.

    I have a laptop (wireless enabled) and last week the wireless worked fine but I noticed my network was not encrypted so I installed the software on my PC and the network is now WPA encrypted and i have my pre shared key.

    My laptop can see the wireless network and when I click connect I am prompted to enter my WPA key which is for example WPA-(6 digits). Then it tries to connect and says "acquiring network address" but this is all it says, it never finds the address but it used to before I encrypted it.

    I have tried the broadband company but they are no help (Talk Talk) and also tried entering IP address in myself but still no luck.

    Anyone got any help on how I can solve this?

    1) the make/model/version of your wireless router
    2) the same for the wireless adaptor in the laptop​
    While it should be true that wireless routers connect <--> wireless latops of
    any mix, the real world experience is (sadly) it doesn't always work --
    especially when the encryption is enabled.

    the usual fix is to get the lastest firmware for both the router AND the laptop
    wireless adaptor.

    then try this sequence of configurations:
    1) connect w/o encryption
    2) try it with the simpler WEP
    3) then with a WPA-1
    4) finally, a WPA-2 (if available)

    stop at that level where it is working AND encrypted :)

    I was told by Talk Talk that my wireless router is made by Philips, model number SNA5630NS/05
    My laptop wireless is Broadcom 802.11b/g WLAN

    How do I change the encryption, how do i disable it?

    >How do I change the encryption, how do i disable it?

    this is done in the router itself -- it controls how systems connect to it.
    normally, you connect the router via cable to at least one system (ie not-wireless!)
    and then use your browser to open the default IP address specified by the documentation.

    Attempting to find some documentation on google.com leads to massive
    concern -- LITTLE IF ANY FOUND!

    HOWEVER, you might like to see this blog re Phillips + Talk Talk

    I entered the DNS and IP settings myself and it shows up as being connected, even some small bits of data are being transferred.

    But when I enter the browser, I cannot view anything and get the Cannot Find page all the time.

    Starting to p' me off now.

    normally, we use DHCP to get both the IP and DNS addresses.
    WHY? You just stumbled into it -- your addresses are in question --
    ie: where did you get them from?

    see this post to test your TCP setup

    I have an IP address on my PC 172.168.*.* my default gateway is 172.168.*.*

    I have my DNS setting from Talk Talk so therefore I entered the DNS settings into my wireless laptop, and also the same IP address as my PC gateway into my laptop gateway.

    Then I entered a IP address for my laptop which was the same as my PC but the last number i changed to 1 number higher.

    Would you be able to type out what can be done if you have any idea?

    Would it be worth rebooting the PC to clear the modem and re-install ?

    >my PC 172.168.*.* my default gateway is 172.168.*.*

    is this a typo? normally it would be 172.16.*.*

    without some documentation for your modem/router, I can't give precise
    sequences of things to do -- blame your provider.

    If I were doing this for myself,
    1. I would access the router controls,
    2. set the router to be a DHCP server,
    3. set the default address for your router, like
    4. remove all IP addresses you have entered
    5. save the configuration and power cycle the router.

    now in your systems, use the network wizard to define a new link

    you should then be able to follow this post
    until this works reliably, you will continue to have problems :(
