Hi, a quick question. My 25/5 fixed wireless nbn has been perfectly reliable for years now but in the last 2 weeks the speeds in peak times (after 5)have dropped to a unusable .9-1.3 mbps. Ive reported this to internode a few days ago but I havn't heard back as yet. Is there a way of checking if the problem is the tower itself or a ISP limit? I want to know if changing isp will help - a plus with other isps is they offer the faster 50/20 plans that internode hasn't as yet.
