CAT Telecom in Koh Samui have admitted there is a big problem with their routers.
The machines that broadcast signals for computer notebooks and phones to access the internet have mysteriously gone wrong.
By yesterday 300 angry customers had returned their WiFi routers to the HQ on the island.
Manager Namphon Rakdee said the problem had persisted for three days and he admitted all the routers of CAT Telecom could be affected.
He wasn’t sure of the cause but suggested it is probably some faulty signal causing them all to malfunction.
He urged customers to bring in the routers to get a replacement.
He expected the problem to grow in size in the coming days, said Sanook.
