Randomly the internet connection for either my, my son's , or my husband's pc drops. This also can happen with the X-box. The router lights indicate it is working and the rest of the connections will be fine just randomly any one of ours will fail until we reset the router. Two of the pc's are wired, one is on a plug (devlo) and the xbox is wireless. I phoned BT, our isp, who sent an engineer out. It turned out the BT rep told the engineer I had reported no dial tone on my phone line and if I had allowed them to investgate this fictitious fault it would have cost me £150 for a call out. They then suggested the router may be faulty but insist I renew my contract before they will help to see if they can get my service working properly. Any ideas?
