I’ve been on the phone with Encore, with Hawking, and with ATT, who (as SBC) sold me the 2Wire router/gateway/modem for my dsl. We’ve turned off the firewall in the computer, and turned off the encryption on the router. I can’t add this computer to the exceptions on the router firewall, but everyone says that it should be automatically added to the list of things to except, but it never is. The connection dialogs constantly say “Limited or no connectivity”, and complain that the network has not given an IP addresss. Even ATT agrees that it is not the problem of the adapter, except that after about an hour of troubleshooting, the support guy suggested getting a more name brand adapter.
I know this is shooting in the dark, but if anyone has any kind of suggestion, I’d like to hear it, rather than run through buying different brands of adapters.
I recently had a problem similar in which I discovered: when you hook up, the internet provider’s side (in our case, at least) talks to whatever device makes contact first (which in our case was the desktop computer), and keeps track of that MAC address or whatever its called, to avoid . . something (hence when we then hooked up the router it didn’t want to talk to this alien MAC address). So to get it to accept talking to our wireless router instead we had to do a hardish reset (unplugged it for several minutes). Perhaps your problem is similar?
The adapter/computer sees the network, and says it’s connected, but at the same time says “limited or no connectivity”. Then other dialogs say that the network failed to give an IP address.
Where are these logs? No one has suggested this to me.
I’ve tried to research mac addresses, but I don’t truly understand if I can just make one up, and I don’t know what number to use or how to input it.
I’m not asking for someone to necessarily give me a course on this, but that’s where I’m at. I’ve never had to deal with networking much. I’ve never run into this, and my router works just fine with my D-Link PCI card. I can’t tell if it hates USB adapters or all other computers.
The ATT guy had me unplug the router for a minute. That didn’t seem to affect anything. Is there any reason, good or stupid, that a router might reject everything after the first connected device?
It may be that you just skipped over mentioning it, or I’m misunderstanding, but I don’t see anywhere you mentioned going into the wireless configuration and seeing a list of available networks, telling the adaptor to connect to a specific one, and setting things like encryption, etc. Depending on the driver, this might be handled by Windows Networking or by a separate manufacturer-provided connection utility. Some network adaptors need to be explicitly told what to connect to, even in the absence of encryption.
