Once again the sun sinks into its nightly reprieve; for the third time since I first set out on this mission. Before me, only the piercing glows of monitors that sting my eyes. Yet, I cannot look away. The clacking of keys, once triumphant battle drums of purpose, has grown sharp. They pierce my ears and my mind. It would be madness to continue. My body is weak. My resolve is waning. My sanity ...... tenuous. But if seeing this through means madness.... bring on the madness. :pt1cable:

Hi. Matt here - long time listener, first time caller. Alright, so I'm trying to find a way to network my desktop (wired) and my laptop (wifi) so that I can swap files between the two easily. I’ve mostly been attempting this through Windows Homegroup, although I've also downloaded and installed TeamViewer. The thing is, the two just will not connect. After much poking around I found the specific symptom to be that wired connections and wireless connections refuse to speak. My laptop sees my roomie's laptop easily enough, though. And if I hardline my laptop to the router suddenly their best friends! - joining each others' Homegroup, swapping files, trading recipes!

  • I’ve noticed that, while both are enabled, only IPv4 connectivity indicates internet access; IPv6 says “No Internet Access.”
  • I believe I have them set on the same workgroup - I changed from the generic "WORKGROUP" name to mitigate possible interference from roomie's machine but have no indication they're connected in any way.
  • Pings from one machine to the other result in "Request timed out" or "Destination Host Unreachable."
  • I've disabled firewalls: both Windows and the one on the router.
  • I disabled and then uninstalled anti-virus.
  • I've alternated static and dynamic ip addresses - the issue isn't shared ip addresses.
  • I have sharing options turned on and have specifically selected individual folders to be shared.
  • I've updated the router firmware and net adapter drivers, and even tried resetting router to factory settings.

    I've spoken with Belkin tech support, but that automated which-way book didn't get me anywhere. When I run through Windows diagnostics, I can almost hear laughter coming from inside the machines.

    I'm at a complete loss. I'm knowledgeable enough about computers, but networking them together - forget about it. Does anybody have a clue what might be going on? Are there any other programs other than firewalls or anti-virus that are known to interfere like this? If anybody has any clues or suggestions, my sanity thanks you.

    (Forgot to mention: Windows 7 on both machines - professional on desktop; home premium on laptop)

    Hm, I've just spotted a couple of errors in the Event Viewer that look like they could be leads;

    (!)Error Dhcp-Client
    The IP address lease 192.168.2.2 for the Network Card with network address 0x6CF049E337F0 has been denied by the DHCP server 192.168.2.1 (The DHCP Server sent a DHCPNACK message).

    (!)Error bowswer

    **GLADOS is my laptop's name. The error is from my desktop.**

    Thanks for the [ehem] VERY detailed post, but let's get back to basics:

    In your router settings, are wireless connections allowed to communicate with your LAN?

    Does your router also support guest wireless connections, which normally only have Internet access, and are you accidentally connecting to that?
    May 11, 2011 2:55:47 AM

    Heh. Sorry if I went a bit overboard. I'd been doing quite a bit of posting in forums, and every thread was just cycling me through posting all of that stuff, so I thought I'd just try getting it all out there right off the bat. I had half a mind to toss my blood type and favorite color there at the end.

    Alright, I'm looking at my router's setup page. I'm not seeing anything along the lines of guest wireless connections. .... Hm, I'm doing a little research on some of the settings I didn't understand, and this "Use as Access Point" sounds pretty damn promising. The router page doesn't say a damn thing about what it means, but according to Wikipedia:

    Quote:
    In computer networking, a wireless access point (WAP) is a device that allows wireless devices to connect to a wired network using Wi-Fi, Bluetooth or related standards. The WAP usually connects to a router (via a wired network), and can relay data between the wireless devices (such as computers or printers) and wired devices on the network.


    Yes, I'd say that sounds pretty damn promising, indeed!!

    Your Wireless router is a "wireless access point". Both computers are on the same subnet, so they should "talk". My first thought would be that HomeGroup settings on the NIC and wireless card are different. Check those settings out.

    Also try and turn off/disable the computer browser service in services.msc, usually that only is turned on in a Domain environment. There is a regedit that will work too, but ill have to find that...



    May 13, 2011 3:05:46 AM

    Well, I tried initiating the "Use as Access Point" setting, and promptly locked everyone out of the network. =/ Got it back up and running now, though.

    I'm thumbing through adapter settings, but nothing jumps out at me as amiss. Both are setup to obtain ip addresses and such automatically. Is there something specific I should be looking for?

    Just one year late to the party...had matter, did you resolve this? having same problem. Seems all threads regarding this topic end unsolved.

    Ha! Yeah. I did find a solution, of sorts. I bought a new router. =D No muss; no fuss on sharing with this one. I highly recommend that. The one I got is the NETGEAR 750 which was pretty high end at the time. When it comes to technology I don't fully understand I choose to er on the side of excess. Of course, I'm sure there are many viable options.

    If forking up some cash isn't an option you might want to take a look at third party router firmware. I learned about these after buying a new one, but I feel like I read a testimonial of someone who had fixed this problem with one of these. Also there were tales of people unlocking previously unavailable functionality and such. I believe DD-WRT were supposed to be "THE" 3rd person people to use. That's about the only leads I have for ya.

    LOL! Check out that opening bit of maniacal poetry in my opening post! WTF!? XD

    Good luck to you in your fight, Vince.

    Thanks for the response...didn't think I'd reach you after a year+. Got a new router today and still nothing...wondering if one of my wired gadgets is to blame? I Tried eliminated and adding one at a time but hasn't revealed anything.

    Anyways. I'm frustrated and rather addicted to solving this. Haven't explored 3rd party firmware yet. will check that out.
