I could really use some help trying to sort out a problem I am having. In my home I have 5 computers, 2 cell phones, 1 tablet, 1 smart TV, and a Direct TV Whole Home DVR system. All of the devices except for 1 of the computers connect wirelessly to the internet. My problem is this:
Every day or two, at least one of the devices will not connect to the internet even though they always seem to join my network. When I let the computers try to fix themselves via Windows, I always receive the message “invalid IP address”. Sometimes Windows can fix the issue, sometimes not. However, a quick reboot of the modem (unplug, wait 10 seconds, re-plug) always resolves the problem. The wired computer never loses internet connectivity.
Although I have very limited knowledge troubleshooting networks, this indicates to me that something is wrong with my DHCP. I suspect I may need a new router although the signal to all of the devices is very strong (indicates excellent). My download speeds are also great when the devices connect. I currently am using a D-Link DIR-655 router, and a Motorola SB6141 modem.
I don’t mind purchasing a new router, but I do not want to start blindly throwing money away without having some idea of what may be happening. So, can any of you knowledgeable people perhaps offer some assistance as to how I can possibly isolate the issue?
Thank you very much in advance
