Hello,

I have 4 pcs in a home network.

PC 1 connected by wire
PC 2 wireless
pc 3 wireless
laptop wireless

Problem one is that dhcp will only give ip addresses to the wired pc but not the wireless pcsl. This has always been the case despite the router I have used.
Its only a minor problem as I have set ips in all pc's anyway, but its just annoying that its never worked like it should.

Problem 2 is that pc 3 seems to change its mind about how it will connect to the internet.

For example its settings were this.

ip 192.168.1.4
subnet 255.255.255.0
default gateway 192.168.1.254

DNS

preffered 192.231.203.132 (these are my ISPs dns addresses)
secondary 192.231.203.3
And it wouldnt connect so I changed the preffered DNS to 192.168.1.254 and then I had a connection.

The next day no connection so I changed it back to above and it worked again. Then just now no connection so I changed the dns back to 192.169.1.254 and connection works again.

So what exactly is going on here? Also should I be using the DNS adresses supplied by my isp on the network pcs, or the routers Ip address instead?

On the main PC1 I have to use my isps DNS or I wont connect to all web pages.

Advice appreciated.
