Be Broadband has advised customers of potential security problems which could arise with their home broadband routers.
In a statement to customers, the broadband provider claims it has been informed of the potential flaw and is automatically updating the password for its router.
The statement said: "Essentially, the problem could allow somebody to change your router settings, and nobody wants that."
Be claims setting the password on every customer's router box will "stop this from occurring" as if someone attempts to hack the router, then they will be prompted to enter their administrator password.
The firm recently announced that its Be Unlimited and Be Pro broadband packages were available for only nine-month contracts for students ordering through its website before October 16th.
