Suddenly cannot acquire an IP address.

By tes4444 ·
My laptop suddenly cannot acquire an IP address. I've lost connectivity to our wireless router in the past and had to reboot to reconnect, but this is a new problem. I can't acquire an IP address at all. My wireless card sees the router and connects just fine, but gives me the old "limited connectivity" message.

Here's where things get weird. I cannot even get an IP address when I cut the network out of the picture and plug the laptop up directly to the cable modem. I've gone so far as to reinstall all of the hardware and reconfigure all of the connections, both automatically and again manually. No dice.

This baby was working fine when I went to sleep last night and is otherwise running fine still. At every step my desktop connects just fine through the same devices that the laptop. No changes were made to the laptop to cause this. Anyone have any ideas? I'm banging my head against the wall here.

Try re-posting as a new question in the Q&A section. The 'Discussion' forum is for matters of general discussion, not specific problems in search of a solution. The 'Water Cooler' is for non-technical discussions. You can submit a question to 'Q&A' here:;content

There are TR members who specifically seek out problems in need of a solution. Although there is some overlap between the forums, you'll find more of those members in 'Q&A' than in 'Discussions' or 'Water Cooler'.

Be sure to use the voting buttons to provide your feedback. Voting a '+' does not necessarily mean that a given response contained the complete solution to your problem, but that it served to guide you toward it. This is intended to serve as an aid to those who may in the future have a problem similar to yours. If they have a ready source of reference available, perhaps won't need to repeat questions previously asked and answered. If a post did contain the solution to your problem, you can also close the question by marking the helpful post as "The Answer". .
