I asked this question, which got a great answer, but was voted to close. My question is, why? From what I can see, it appears to be well within the scope of the site (networking). Are the use of WiFi extenders considered to be non-professional grade?
While your situation is pretty unprofessional, you're essentially guaranteed to have long term issues due to the hardware/configuration, I don't think it's off-topic for SF. I've re-opened the question, though there's nothing stopping people from closing it again.
I'm a bit dismayed that none of the people who voted to close left any comment with their reasoning. Usually someone leaves a comment, unless it's painfully obvious (which isn't the case here).
