Today, for the first time, when I clicked on the Forum shortcut, I got this!

Even if I don't use the shortcut, and type "bb.steelguitarforum.com" into the address bar of the browser, I still get that error message. Notice how the URL at the top has been changed from what I typed ("bb.steelguitarforum.com") to "mywifiext.net"!
On a few occasions, I have seen a popup box from mywifiext asking me to log in, which I won't do because I don't trust it.
Now none of this happens if I enter a URL of "www.steelguitarforum.com" (i.e., not using "bb."). Why should that matter?
Finally, if I connect directly to the (weaker) signal of the modem, instead of to the extender, it works fine even with the "bb."
So why should my extender have a specific problem with "bb."?? What's going on here?
Thanks in advance,
Jim
