BT is known to update their gear behind the user's nose so go over all of BT's settings and then try connecting to BT's own gear directly. If the extender fails, consider it failed and get it replaced.
I have this little gadget and it was working fine.... all set up and my laptop connected, etc. Then I took my laptop away and when I came back, it will no longer connect with Internet Access. The lights are all on on the Extender. The laptop finds the Extender in the list of Networks, and it connects but will not give me Internet access. I've tried unplugging the extender, resetting the extender, and twisting my nose while holding my breath. Nothing seems to work.
I am using an HP laptop, Windows 7, on a BT Infinity network. I also tried connecting my Samsung Galaxy S4 smartphone (wifi connection) and get the same thing: it connects, it says, but no Internet.
What am I doing wrong?
