IP Conflict -- home network goes down

[BigFatMeanie]

I do that in my router control board, right? the 168.1.1.2 thingy?

Camleish has given you instructions for how to ensure that your PC/mobile device is using DHCP. If they're all using DHCP you really shouldn't have a problem so go through Camleish's steps first to make sure ALL your PC/mobile devices are using DHCP.

If there is still a conflict it means that your router is somehow giving out the same IP address to two separate devices which is very, very rare but not impossible.

My step is a more complex step to try and prove out whether the issue is really a DHCP conflict between two devices.

In your router configuration, you can assign a range for the dynamically allocated IP addresses (DHCP). For example, you can tell the router to use the range of 192.168.1.2 through 192.16.1.10 for DHCP.

You can then tell one of your PC/mobile devices that you think is conflicting with the other to use a static IP address that's outside the range, say, 192.168.1.77. If the problem persists then you know it's not a DHCP or IP address conflict issue but some other type of problem.

It sounds as though there may be too many devices for the IP range. Log into the router and see what the DHCP range is.

That could be it.

I tried Cam's suggestion, and I was already set up that way. I tried this suggestion, and it seemed to have worked. I set up the new laptop as a static IP out of the range and all good so far.

Interesting.

So, can you verify that you don't have too many devices for the DHCP range as others have suggested? In other words, if your DHCP range allows only 5 addresses but you have 6 devices then you'll have issues.

After a Google search it appears the default DHCP range of .100-.254 on Netgears. So unless the range has been altered, then that probably is not it. So I am a bit stumped. I wonder if it could be a reserved addressing issue.

This actually didn't work. It lasted longer before it went bad, but it still went bad. I'd have to disconnect and reconnect, and then it would work for a half hour before going bad again. It's been very frustrated. I read some google threads, and tested a few things. The thing that finally DID work...upgrading my router firmware. Strange.
