I have a local cable operator and it was previously setted up to 100 Mbps half duplex and it was working fine but after some days it was showing "unidentified network" So I changed it to 10 Mbps half duplex and it was working fine. But when I was downloading I saw that it was not increasing at that speed which was used to go before and when I have shifted again to 100 Mbps half duplex it was showing the same error which is "unidentified network" please help me.
