@stealth23 Ok, there have to be something wrong with the router, I would return this router and ask for a new one., it should easily manage 350Mbps, I have several ER605v1 on 350 and 500Mbps lines...

@stealth23 What speed have your internet?

@SingletrackMind SHA2 don't work in controller mode, only in stand alone. Settings is there but even if you use SHA2 router use SHA1, More information in this post...

@Solla-topee I have factory reset my P115, no different other than all my historic data is gone.

@Fae When is the beta firmware for the ER605v2 ready?

@butch_bs I don't think so, it looks like this product has been end of life since 2018
