2 PCs in network unable to "see" each other

Post by Ubtree » Mon May 11, 2015 9:49 pm

I have been operating for some time without problems with a home network based on a Billion BIPAC 7800N modem router. The devices in the network include 2 PCs - one connected by ethernet cable to the router, and the other (usually) by Wi-Fi. Until now, I have used the router's DHCP server to allocate IP addresses, but am now allocating static IP addresses to each device.

I have set the gateway's (and the DNS server's) IP address to, with Subnet mask I have allocated the IP address to the ethernet card of the first PC, and IP addresses and to the ethernet card and wireless card of the second PC (with the same subnet mask as the router).

Connecting the second PC using the ethernet connection gives no problems.

Connecting the second PC using the wireless card prevents either PC "seeing" the other, but both PCs can access the internet.

Can anyone advise what I need to do to enable the same full network connection with using the wifi card on the second PC, as I have when using the ethernet card?

You might try the Level3 DNS's of and - or - and

They're pretty fast and reliable.

Alternatively you could try any of these

Comodo - and

Google public - and

OpenDNS - and


If you want to find the >>fastest>> DNS server for YOUR location you could try running Steve Gibson's free DNS Benchmark
