Okay guys, I have a problem I can't figure out for the life of me. On my other (desktop) pc, I can't connect to the internet. We have a cable modem in our house, but it isn't in my room. Our house is wired for a small network, etc etc...So anyways, I can connect to the internet on my laptop, but the PC wont connect. What's wrong? What should I try? I've tried re-installing the drivers on my other PC, tried different cables to hook up to the network, but nothing seems to work. Do you guys have any idea on how to fix this?
oh great...someone tells me what happens if your computer is on and metal touches the motherboard... i think i just fried my computer...
The cable modems are setup to only provide you with one IP address by way of DHCP. In otherwords, they only let you have one system on the 'net at a time. Your choices are: 1. (My solution) Get a 'internet sharing device'. An example would be the Linksys Etherfast Cable/xDSL ROuter. This, IMHO, is the best solution, but also the most costly. It also provides you with some basic firewall stuff, as it uses something called 'NAT' to hide your addresses. 2. You can get 2 ethernet cards for your primary machine, and use some form of sharing, either through the 'Windows 98se/ME modem sharing' feature. For this you'll have to get an additional NIC for your primary machine, and it's a pain to setup and use. It is, however, cheaper. I'd be glad to answer any questions you have about either of these setups.
Pull the plug, wait 3 seconds, plug it back in, and try to turn it on. Most grounding issues will simply result in the machine shutting down, without any imediately apparent problems.
you misunderstood my question, i think... Computer A has always worked under the current setup. Computer B has always worked under the current setup. Computer A stops connecting to the internet. Computer B still connects to the internet. SirCharlesFan cant figure whats wrong with computer A, but it doesnt matter because he thinks he just fried Computer A....
In 4 years of breaking people's computers, I've yet to completely fry someone's computer (except for the time I stuck a screwdriver through the blades of the power supply and melted halfway through my screwdriver by grounding the +12v feed. Thank god for insulation). In this time, I've grounded countless MOBO's and pluged in countless Molex connections upside down. In short, it's difficult to fry a MOBO. If it's ATX, try disconnecting the connection to the MOBO and waiting a few minutes. I'm almost sure that it'll work. Post if you get it back up and I'll give you some ideas about what to check for the I-Net.
Try: Start->Run. In the White spot type 'command'. When the black dos window comes up, type 'ipconfig'. Tell me what it says.
odd. Windows IP Configuration 0 Ethernet adapter : IP Address 0.0.0.0 Subnet Mask 0.0.0.0 Default Gateway 1 Ethernet adapter : IP Address 0.0.0.0 Subnet Mask 0.0.0.0 Default Gateway
Ok, you aren't even getting an ip address. This most likely eliminates a virus as the problem, but there is a whole host of things that it could be. From that same command line type 'ipconfig /all |more'. Then note which of the two (ethernet adapter 0 or ethernet adapter 1) is not Dial-up adapter. This is the one we have to worry about. Please let me know which one it is, and what it says. Locate your ethernet adapter on the back of the PC. There should be a category 5 cable (ethernet cable) running into it. Furthermore, depending on the type of ethernet card, there should be several open spaces for lights, and some of them should be lit. Tell me how many there are and how many are lit. Then go 'start->settings->control panel->network' and let me know what appears in the big white space. (It should start with: 'Client for Microsoft Networks'.)
there's only 1 light on my ethernet card and whenever i plug the ethernet cable into it, the light will blink occasionally. not on any sort of pattern that i can see... as far as that other information, i dont see where it says which one is the dial up adapter or anything....I dont have a regular modem hooked up to the computer right now, if that is what you are asking... on both 0 and 1 ethernet adapter in the dos prompt, the information is exactly the same Descpription: PPP Adapter. Physical Address: 44-45-53-54-00-00 DHCP Enabled: Yes IP Address: 0.0.0.0 Subnet mask: 0.0.0.0 DHCP Server: 255.255.255.255 thats the only information with the blank filled in...
and for your 2nd question: Client for Microsoft Networks Dial up adapter dial up adapter #2 (VPN support) Microsoft Virtual Private Networking Adapter Realtek RTL8029(AS) PSI Ethernet Adapter TCP/IP Dial Up Adapter TCP/IP Dial Up Adapter #2 (VPN Support) TCP/IP Realtek RTL8029(AS) PSI Ethernet Adapter
Ok: So, we have two dial-up adapters in 'ipconfig', but three: TCP/IP Dial Up Adapter TCP/IP Dial Up Adapter #2 (VPN Support) TCP/IP Realtek RTL8029(AS) PSI Ethernet Adapter in the networking control panel. IMHO, it sounds like 'PnP OS' isn't enabled in the BIOS. Assuming you have a fairly generic PC, reboot, hit delete several times, and if you get a deep blue screen with white lettering look for a screen that says something about PnP. Go to it and make sure that 'PnP OS' is enabled. Then, boot back into Windows. Go to the networking control panel. Remove every instance of TCP/IP. Then click 'install->protocol->tcp/ip'. After this, it should ask you to reboot. Do so. When you get back into windows, try to get to the internet. Let me know if this doesn't work, or if the options are not as I have said. Depending on the PC manufacturer, they might be different.
How exactly is each computer connected to the cable modem. Generally the cable modem is set up to have the cable coaxial wire as input and an RJ45 (patch cable) as output. From there, you can go directly into one NIC into one computer or you can go to an ethernet hub, switch or router. If you go into a Hub, you generally go into an 'uplink port' with the RJ45 cable. From there you have a number of outputs and each one will have an RJ 45 cable going into a computer NIC card. With this setup you need to have your cable company provide at least two IP addresses. Running the winipcfg command on both computers will show you if you have an IP address. Go to Start->settings->control panel->networking Highlight the TCP/IP connection for your computer's network card. On the 'IP Address' tab, make sure 'Obtain an address automatically' is checked. Also, check the 'Detect connection...' box. On the 'WINS Configuration' tab, make sure 'Disable WINS Resolution' is checked. Everything else should be blank. Everything under the 'Gateway' tab should be blank. On the 'DNS Configuration' tab, 'Disable DNS' should be checked, everything else blank. On bindings you MAY have some things in there. Check them all. Whatever is in 'Advanced', leave alone. You don't necessarily need to worry about the 'NetBIOS' tab. Make sure both computers are set up the same. NOTE - whenever you change any newtwork settings, you will need to restart the computer. If you don't change anything, click Cancel instead of 'Apply' or 'OK'. ANOTHER NOTE - I am assuming this is on Windows ME or 98.
ok guys, i've been playing around, and now when i do 'ipconfig' i actualy get ethernet adapter 0, 1, and 2. On ethernet adapter 0, i get an IP address now, but the net still wont work for me...
SCF What is the IP address that you get? If it starts with 169, then it is most likely a bad address. Again, how are you connecting both computers to the cable modem? Are you doing it through a hub, switch, or router?
bobrek--the ip is 24.116.96.178 as to how i'm connecting to the cable modem...um, we have a router on the computer with the cable modem, I think. as far as what I plug my computer into, we had my room professionally wired and i just plug it into a jack in the wall.. btw, do you have any messaging service like AOL Instant messenger?
I can ping your IP address so that is working. If you have a router, then you should be seeing a different sort of address. The address you provided is the one your router should get from your cable company (cableone.net). Your router, in turn, should distribute a local address to each of your computers (e.g. 192.140.1.100). This allows you to only need the one IP address from your cable company. There should be a way to have a look at your router. Enter the following into your browser: http://192.168.1.1 See if you get to your router. I don't use IM, but you can email me directly: bar@cray.com
Ok, go to a command prompt, and type 'ping 216.118.30.17'. If this returns: 'reply from 216.118.30.17...' followed by other stuff, that's good. In that case, try 'ping www.yahoo.com'. You should then get back, "pinging www.yahoo.akadns.net' followed by an ip address and more of the 'reply from 64.58.76.222' stuff. If this happens, let me know and we'll go from there. If at any point, however, you get the response: 'request timed out' That's bad. Let me know and we'll go from there.
yeah, i got 4 ping timeouts. the reason you might have been able to ping my DNS is because 2 of our computers are still hooked up and working...but i dont know...
