In this case, all the computers we are testing with are wired -----Original Message----- From: [email protected] [mailto:[email protected]] On Behalf Of Scott Reed Sent: Thursday, July 10, 2014 6:27 AM To: Mikrotik discussions Subject: Re: [Mikrotik] Throughput Problem on Mikrotik RB951
This one may be something for the OP to look at. If the customer is connected wireless on b at 11Mbps, 3-5M is about all they will get on a speed test. If the customer is connected faster, then maybe it is something else. On 7/9/2014 6:38 PM, Scott Lambert wrote: > I use a RB951Ui-2HnD wirelessly at my house.
