arduino toggles relays very well, through net, but html page dosent load when lo

I am controlling relays through arduino and ethernet shield

The html page toggles the relays very well when no a.c. load is applied to the relay

But page stops loading when a.c. load like fan or bulb is connected

What could be the problem?

If it's a problem with the relay is there a relay I can buy which can not disturb the working of the arduino and Ethernet shield
