Is there a plug in broadband meter I can connect to my router which is a BT3 hub. Not an application as We have several devices using the wireless broadband so need it connected to the Hub. I have looked at the router itself but it doesn't allow for monitoring. To cut a long story short I changed to BT infinity 4 months ago " big mistake" and since then I'm told I'm over my 40gb allowance even though I check the day before the end of my data cycle and I have only used 32 gb. BT has its own data usage site but this will only show my present month and doest give enough detail to argue the point. What then follows is an additional £10 charge from BT. I don't believe I'm using this much as we don't download movies etc. Bt could tell me I'm using 100gb and I can't say otherwise!
