High Latency on LTE Interface
Hi Guys, Have a Telstra 4GX dongle plugged into an RB2011. Don’t know why, but I am getting randomly high latency from the Mikro to the dongle. Would’ve thought it should be <1ms given it’s plugged directly in?

I'd definitely have thought it should be sub-1ms reply time. If you ssh into the dongle, what is the CPU load looking like? I've disabled quite a few non-essential services on my Telstra dongles, to keep the CPU usage down. On 27 July 2016 at 09:02, Dave Browning <dave@sentrian.com.au> wrote:

How does one SSH to these dongles? I just tried that and TELNET and got ‘connection refused’ Dave Browning | Network Engineer P 07 3369 7666 Level 1, 12 Railway Tce, Milton QLD 4064 From: Public [mailto:public-bounces@talk.mikrotik.com.au] On Behalf Of Damien Gardner Jnr Sent: Wednesday, 27 July 2016 9:07 AM To: MikroTik Australia Public List <public@talk.mikrotik.com.au> Subject: Re: [MT-AU Public] High Latency on LTE Interface I'd definitely have thought it should be sub-1ms reply time.
