We have a phone line with a simple adsl connection away from the main corporate wan at work. It serves its purpose well for no frills wi-fi and browsing the net, its been in place since about 2005 and up until very recently its worked perfectly. Suddenly, the router (a very old Lynksys model) is showing consistent packet loss and tho it will make a connection to a site, its dropped soon after. The odd or email or message will come through etc via whatsapp but thats about it. It was literally working fine at the end of a shift, arrived for the next and this happened. A tracert shows the odd ping timed out beyond the router along the hops to BTs network. We cannot change the router as the password for the bt account is encrypted and the person who set it it up is long gone, likewise BT wont speak to us without the account holder. Any ideas?
