Connection speeds are bouncing all over

Question

Something has happened the last week and I am stuck.&nbsp; I have the Premier package and would regularly use speedtest to check the connection on my ipad. Download speeds always were in the 25-40 mb range.&nbsp; All of a sudden started having a problem. My speed levels are flucuating like mad, usually downward. See it at night when streaming tv is constantly buffering.&nbsp; At&nbsp; 7:15 this morning same thing. Ihad gone into my modem, a Netgear WNDR3700 and checked settings. I contact Zoom about my 6 month old modem. It is Zoom 5341. I have provided a screenshot from this morning. They told me that the controllables/uncontrollables were way out of line.&nbsp; Having read some of this forum, I did some speed test this morning. I ran the test on my wired pc and my wireless ipad at the same time. First test result wired download 4.78mb&nbsp; ---&nbsp; wireless 1.70mb.&nbsp; I then ran the test immediately again. this time wired download 9.76mb &nbsp;&nbsp; wireless 27.81mb. The wireless blew away the wired. Again, these tests were going on at the exact same time. Looking for answers. Nothing has changed the on my end the last two weeks, same equipment, same usage etc.. Why all of a sudden the problem

There definitely seems to be a problem on one of the channels where the SNR is 23.2 dB - with severe frame corruption.&nbsp; Try power cycling the modem to see if it can try to avoid the 933MHz frequency.&nbsp; Check your connections/cables - reseat all connections, make sure there is no build-up on any of them.&nbsp; If you have a splitter, try bypassing it.&nbsp; Check where the cable comes into the building, etc.

I'm located in Las Vegas NV and have the same issue. Its been bad for over a month but lately its daily and aggravating as heck. Ours is just as low and lower in some cases.

Here is our test results. We have the same Premier package.

Bah text overload - I'm not even going to try to interpret that.&nbsp; If you are on premier, my recommendations above stand - check your cables, try it on wired etc.

Although I have reset my modem several times, I will take off all the connections, reinsert them and try again. I will also put a new coax cable on. I have no splitters. What might I be looking at on the outside of the building? As a FYI, that channel 6 "unknown", I am almost positive I saw the SNR earlier at "0" when I got a speedtest result of .88 mb, yes under 1. Sent me off on a internet search of what SNR stood for. This morning it was back to what I posted. I just check now when I got home and SNR at 32.8 and download speed at &nbsp;61mb. &nbsp;Is the SNR supposed to jump al over like that? Seems to coincide with the poor performance. Oh, since this morning when I took the screenshot, I know have 227,000 uncotrollables on that same channel. Thanks for any input you can provide

In your case I suspect the issue is a modem not capable of delivering consistent speeds at that level.  I'd suggest upgrading to a modem with minimum 8x downstream channels.
