Problems like this are usually down to hardware or drivers - please make sure you have the latest sets in place and check that you have the manufacturers drivers and not the ones from Microsoft. Thanks for the advice, tw0rld and Albert. Albert, I'm sorry to be clueless again , but I don't know how to check to make sure I have the latest drivers in place or how to get new ones I especially don't know how to get new ones without internet access! Can you walk me through how I can check to see if I have the manufacturer's drivers rather than Microsoft's?
Thanks so much. See if this fixed it. Let us know? If they have either a red or yellow mark over them then you have found the problem but I would be surprised as you have managed to get a response to ipconfig.
Right click on the network device and look at the properties - click on the driver tab and then driver details. Look at the drivers list and the provider - which should not show Microsoft as their drivers often cause trouble. If they are MS, you will have to locate the latest set for the device or reinstall them from the motherboard CD if you still have it.
Let us. Albert, thanks for these ideas. It's not been preset. The ethernet driver is Microsoft-supplied, but since it's not changed I don't know why it would suddenly give me problems. Also, the wireless card driver is from the company, and I'm getting the same problem whether I plug directly into the ethernet or whether I use wireless Is there a way to download drivers onto another machine, put them on a USB, and transfer them?
Dont worry about the DNS servers - it will work as it is. The drivers might have been changed by an update and you should change the 3Com drivers if you can, You can download the drivers and save them to a flash drive without problem - go to the 3Com site and download the drivers from there and save instead of run the file.
Thanks again for the idea. I re-installed the wireless card software including driver this morning and had a few blissful minutes of internet access -- long enough to update some virus software, and then it disappeared again. Or, more accurately, after I re-started my computer the connection went wonky and then gave me a "Limited or no connectivity" message. So I had a moment in the sun and now I'm backed to stumped. I am currently trying to download the driver for the ethernet controller.
I have had no luck finding the driver on the 3com website -- even in their archive, I turn up nothing -- but the driverguide website has turned up some possible hits. I'm just not sure which of the three I found there is the right one. As far as Driver versions go, should I pick the newest-sounding one the highest number? Or the number closest to what I currently have? Thanks for that idea, CCT. That seems to be the same file name although very different file size of one I have just recently tried, and that didn't appear to help.
I've tried two new drivers so far and I will try this one you've suggested, CCT , and neither has changed anything: when I plug into an ethernet cord I still get the message saying I am connected and the connection is good, but I cannot actually get online or surf the web, etc. That is, if I ping a good IP number, I tend to get fine replies -- 4 packets sent, 4 received, none lost, etc. But if I try to ping yahoo or google, it doesn't recognize the name? Cut and paste this to Notepad and save as Flush.
Got a fix! CCT and Albert, Thanks for all your help and advice. I ended up getting a fix from the ISP technician, who came out to examine the modem and then nicely checked my computer. It turns out that it did have something to do with the DNS staying locked on the same two addresses. He went deep into some folders I know not where and removed some WinSock2 info, and did some other magic, and lo and behold, the DNS now is set to automatically find addresses rather than fixed on two addresses, as it was previously.
