When you look at how many DNS lookups and TCP connections are involved in displaying a webpage, often in a sequential process, I think it does matter.
Someone with a fast computer will notice. Someone on a phone or tablet not so much due to CPU limitations. 5 ms latency and local DNS servers can knock peoples socks off if they are web browsing or doing interactive tasks. Agreed, they won’t notice 100 ms if all they do is watch Netflix and Youtube. Certainly not on Sling TV.

It used to be customers mainly did web browsing and really noticed whether the websites snapped up immediately or lagged. Now everyone is streaming, streaming, streaming. And websites are more worried about tracking cookies and on-the-fly ad auctions for your eyeballs than responsiveness. Plus people use mobile devices and are accustomed to the higher last mile latency of 3G and LTE. Still it’s a little disappointing to backslide on latency because customers don’t value quick response like they used to. They just want mass quantities of data to watch video, as cheap as possible. I guess gamers still care about ping times.

It took me almost 2 hours to get the two radios to see each other but I finally got them too. I wasn't following the PTP quick start guide like I was told to. When I initially configured the radios I disabled the 2nd port (called WAN) in the manual. For some reason they would not link until I turned it back on. Even though I wasn't using the WAN port.

Units are 25db integrated panels. Did a 40mhz channel test and 80mhz via UDP. I tried a TCP test between two RB2011's and best I seen was 175-180'ish and that was with both 40 and 80mhz channels. CPU seemed to be maxing out on the 2011's. Has UNI-1 bands and ISM bands. I was hoping it had the middle DFS bands but it doesn't :( Kurt Fankhauser Wavelinc Communications P.O.
