Allow more IP connections in the 192.168.. range. Disallow any IPv6 address assignments.
I've been working on this issue for weeks and haven't found a solution. Can anyone make a suggestion?
My network:
Router: Hintron CODA 4582
Clients: 1 Windows 10 Pro hardwired
1 Windows 7 Enterprise Hardwired
several WiFi clients
TV, A/V receiver & 2 media centres hardwired
The problem:
Occasionally the Win 7 computer does not get a correct IPv4 address assigned. When this happens, it is assigned 169.254.0.0. Normally it is assigned 192.168.0.10. The IPv6 address is correctly assigned. When this happens, none of the WiFi clients are able to join the network. The Win 10 computer gets both IPv4 & IPv6 addresses assigned correctly. Rebooting the Win 7 computer does not resolve the issue but rebooting the router does fix it.
I have recently moved and have a new ISP (cable). This same network worked flawlessly on my previous ISP (DSL).
Here is what I have done so far...
-relocated the router closer to the Win 7 computer (shorter Ethernet cable)
-connected the Win 7 computer via WiFi
-replaced the Ethernet cable
-replaced the Router
-full virus scan on the Win 7 PC (AVG & MalwareBytes)
None of these actions resolved the issue.
I'm in a little over my head but my research tells me that when the PC client is unable to get an IP address from the DHCP, an IP address in the 169.254.X.X is assigned to enable LAN connections.
My last corrective action was a router replacement since nothing else worked so, by process of elimination, it seemed that the router was the problem but I've had a failure with the new router.
I though that it might be something in the Win 7 PC since the Win 10 PC didn't have a problem. However, it didn't have the same problem with my former ISP. In addition the failure also disables the ability of WiFi clients to join the network.
So.....
I'm at a loss. Does anyone have a suggestion?
