    Long story short-

    Had a Netgear Wireless Router MR814v2 (802.11b) hooked to a VISTA PC
    and it worked fine with an XP PC using a Netgear MA101 (802.11b)

    Bought a new laptop with VISTA which wouldn't connect with the Netgear
    Wireless Router MR814v2 since this router's not VISTA compatible.

    Just got a Belkin F5D7230-4 (802.11g) router and the laptop works

    Now my XP PC with a Netgear MA101 (802.11b) adapter recognizes the
    Belkin router, but won't connect. (firewall is off)

    Security set to NONE on router.

    Is this a compatibility issue between a 802.11b adapter and a 802.11g

    Is this a compatibility issue between a Netgear adapter and a Belkin

    Am I just doing something wrong????

  2. Nope. Vista is not router compatible. See:
    "Windows Vista cannot obtain an IP address from certain routers or
    from certain non-Microsoft DHCP servers"
    You might check if there's a firmware update to your routers as this
    problem was "solved" by the router manufactures, since it's beneath
    Microsoft's dignity to admit that they screwed up.

    I guess Microsoft didn't get the memo about how DHCP should just be a simple
    standard and not rocket surgery....

    OK...now I'm even more confused!!

    I already replaced the non-VISTA compatible Netgear router with a
    VISTA compatible Belkin!

    As I said earlier:
    Are you guys saying my XP PC with a Netgear MA101 (802.11b) adapter
    won't work with my VISTA PC/Belkin VISTA compatible router????

    That's my guess, but I didn't think that would be an issue.

  5. That's because you have presented two issues.
    - 802.11b client with 802.11g router.
    - Vista compatibility.
    There's no such thing as "Vista compatible". There's the lame
    Microsoft DHCP glitch, which is easily fixed, but everything else is
    the same with XP and Vista. My guess is that "Vista compatible" is a
    sales gimick.
    - Your XP PC with whatever you own, will work with either the Netgear
    or Belkin routers.
    - Your Vista PC will not get a DHCP assigned IP address unless this
    was fixed in the firmware of either router, *OR* you apply the fix I

    However, I suggest that you consider getting something better and
    faster than the Netgear MA101. 802.11b only clients tend to slow
    everything down on a wireless network. It's not just that the 802.11b
    devices are slow, it's that they hog so much airtime that the 802.11g
    devices have little time left to move their traffic. I wrote
    something on the topic recently:

    OK...you said:
    Unfortunately it worked when I used the Netgear 802.11b router, but
    doesn't work with the Belkin 802.11g router!!??

    If I understand correctly, it then must be a problem with some setting

    Any suggestions on what to try next?

    I'd be happy to replace the Netgear MA101 with an 802.11g adapter if I
    thought it would solve the problem.

    I read your article......an 802.11g adapter should make a performance
    improvement, but do you think that it would make a connection if the
    Netgear MA101 doesn't connect?

    phil6666, Aug 2, 2007
  7. Is "it" the XP computer or the Vista computer.
    If the Vista computer, did you try the DHCP fix I suggested twice?
    If the XP computer, see next paragraph on WEP.
    Maybe. You didn't say anything about encryption. There's a very
    common problem with WEP encryption and converting from ASCII to Hex.
    If you're using WEP, try using a Hex key instead of ASCII.

    Also, if using WEP, be advised that WEP security sucks. If possible,
    switch to WPA-PSK (also known as WPA-Personal).

    Can I assume that you've check the manufacturers web sites for
    firmware updates on both routers and all your clients? If not, do it.
    Driver and firmware updates tend to solve many mysterious problems.
    Yep. Reset everything to defaults, turn off encryption, turn off any
    turbo-G, afterburner, faster than 54Mbits/sec, modes in the wireless
    routers. Just basic 802.11b/g.

    For your 802.11b client, try setting the various routers to 802.11b
    mode only and see if that magically works. There seems to be a
    problem with the "mixed" mode on some routers.
    It may not solve this problem, but it will solve the problem you're
    about to have with performance. Keep trying to make it work, but at
    some point, I suggest you move on to something faster.
    Ummm... yes. Anything that's Wi-Fi compatible and blessed by the
    Wi-Fi alliance should connect. That's the whole idea behind Wi-Fi
    compatibility. However, there are various ways to screw things up. MS
    has their DHCP screwup. The chipset vendors have their WEP ASCII to
    Hex conversion screwup. The various chipset vendors are addicted to
    large numbers, so have added protocols beyond 802.11g that sometimes
    screwup. What I'm suggesting is that your reduce your complications
    to the bare minimum, and try again. It should work.

    My XP computer with the MA101 worked when I used the Netgear 802.11b
    router, but doesn't work with the Belkin 802.11g router!!??

    Firewall and encryption turned off.

    Driver updated.

    Tried router with 802.11b only.

    Uninstalled MA101 software and re-installed.

    Still doesn't connect!

    Can't even see how to change any configuration options for this

    I suppose a new 802.11g adapter is my next try........

    Any other thoughts???

    Thanks for trying!!!!!!

    It really seems like the B adapter connection problem would be in the
    settings of the new router.

    The obvious, which it appears you have checked, is if the new router
    is set to "G-only"

    Another one is if you have WPA encryption that your B adapter won't
    handle. You say you have security off.

    Another possibility would be in the IP address assignment, gateway,
    things like that. After re-installing the adapter, it should be set
    for DHCP, but you could check that to make sure you are automatically
    getting your IP and DNS addys from the router.

    To change the options, open network connections and get to the
    properties for that connection/adapter. See if Windows is handling it
    or not. If not, then go to the start menu and try to find the
    adapter's utility software and open that.

    Complete reset of the router, as Jeff suggested is in order.

    Still, best to just buy the G adapter and move up to WPA. The odd
    problem, whatever it is, will probably go away with the change.

    Reset the router to initial settings- no help.

    Went to Adapter configuration, but everything was "greyed out."

    Uninstalled the software.

    Reinstalled.....wizard goes to completion, but there's nothing in the
    MA101 folder in Program Files!!??

    Going to setup on the CD and manually starting doesn't help.

    Not sure what's going on....the instructions are specifically listed
    for XP computers!!!???

    Time for a new 802.11g adapter?????

    Just hope it works!!!

    Any other ideas?????????????????????????????

    One final question-

    Since my Netgear Wireless Router MR814v2 (802.11b) worked fine with
    the XP PC using a Netgear MA101 (802.11b) adapter before I bought the
    Belkin 802.11g router, can I hook the Netgear router up to the Belkin
    router and have any hope of getting the Netgear MA101 (802.11b)
    adapter on the XP computer to actually work again?????.

    Yep. Sounds like a driver/utility problem mix-up for that adapter.
    Possibly combined with wrong settings that you can't change. I get
    this sometimes. Between windows zero configuration and the utility
    and I don't know what else, they get screwed up. Sometimes there is
    another wireless adapter installed and they affect the settings for
    each other.

    No luck finding the utility under the Start menu?
    Is there anyother wireless device installed?
    Can you find anything for it as a running process? (ctrl/alt/delete)

    Another place to look is in services. Start>run>services.msc look
    for the utility in question to see if it is started. Also see if
    Windows zero config is running. Make sure one is running.

    Finally, go to support for Netgear and detail your problem and/or look
    it up in their forums/knowledgebase if they have them. There should be
    some more specific help there.

    Oh, one more thing. Uninstall everything. Install another adapter.
    Once it works, reinstall the netgear. This may fix it.

    This is why I have two USB adapters and two pcmcia cards. Easier to
    swap them out sometimes to work around or help diagnose the problem.

    Yep. Just run from a LAN on the Belkin to a LAN on the netgear. Turn
    off DHCP and firewall on the Netgear. Give it an address in the same
    subnet as the Belkin but outside Belkin's DHCP range. Set it to a
    different channel from the Belkin.

    I suspect that your adapter is not going to work anymore with the
    netgear either anymore until you find the driver/utility problem.
    But, if it does, check the netgear settings to see what is different
    from the Belkin.

    Sorry I haven't had time to reply to this....

    I simply hooked my old Netgear router up to an open port on my new
    Belkin router.

    Within seconds, the old Netgear adapter on the XP computer was happier
    than a pig in sh.t.

    So, what did I learn-

    1) My new Dell laptop refused to work with the old Netgear router, no
    matter what.

    2) My new Belkin router worked instantly with the laptop, but not the
    old Netgear adapter on the XP computer, not what matter I tried.

    3) Hooking my old Netgear router up to an open port on my new Belkin
    router solved the problem with the old Netgear adapter on the XP
    computer instantly.

    I suppose you just shouldn't try to mix old and new technologies
    unless you have a tremendous amount of time/expertise!!!!!!
