Ever since I've upgraded my firmware on my Buffalo Router and Access Points WZR-1750DHP to the current firmware of 2.27 to fix my QOS issue my Access Points have become quite unstable. They bounce randomly throughout the day. I've called Buffalo technical support and they don't seem to care. Buffalo Tech has said that I can't 'Roll Back' to a previous firmware and all they suggested is to replace them. Replacing them with new units with older firmware wont fix my issue because then QOS will be broken. I noticed NTP was an issue in the previous firmware as well. I currently have that service disabled on my Access Points. I don't know what could be causing this problem or what to double check. Before the firmware upgrade all units were stable. They are all the same make/model.. The actual 'Master' router seems to be stable with the 2.27....just not the AP's. Ideas?
Generally users facing errors in their firmware versions that gets outdated. If you ever since see that firmware 2.27 upgrade to fix QOS problems? Get simplest troubleshooting steps that can able to work on any router device without disconnecting. This happened when a customer is using an online streaming application on a desktop and all the laptops connecting to the Wireless via the internet accessibility. Search around on the internet for DIR-615 B2 and it seem that there is no other alternative. Done factory default by no valid via the Web but still giving me same problem as the Internet seem flaky. Just get to upgrade it from here as listed below. It will come with new features such as like QOS & a Multicast Streaming.
Note: if yet problems facing then we are not responsible for any failure up-gradation of router firmware. We hopefully think that it really works you.
