I have an LHG with an EP06-E module fitted running to a tower about 10km away connected to Telstra. It's been OK for the most part but lately the 4G link has been flapping several times a day, sometime with long periods of silence. The logs show nothing awry apart from the LTE link going down and DHCP not happening. Has anyone else noticed robustness issue with this module? I have set system reboots at 5am to try and help but it keeps happening through the day.
G'day Jason, There are a relatively large number of those "in the field" and not any similar reports that I'm aware of :-l Could it be a signal level thing? Or someone gone and purchased a '4G repeater' from dodgy vendor and causing local trouble? : ( What sort of rx levels is it registering for LTE? Generally anything better than -100 is usually OK to be 'stable'... Did you try enable debug logging on LTE messages to try to find out if there is anything else it can report about why the link drops? -----Original Message----- From: Public <public-bounces@talk.mikrotik.com.au> On Behalf Of Jason Hecker via Public Sent: Sunday, 12 November 2023 7:52 AM To: public@talk.mikrotik.com.au Cc: Jason Hecker <jason@upandrunningtech.com.au> Subject: [MT-AU Public] EP06-E dropouts I have an LHG with an EP06-E module fitted running to a tower about 10km away connected to Telstra.

Hi Mike, Thanks for the suggestion, I have LTE debug going to disk now. Regards, Jason Hecker On Tue, 14 Nov 2023, at 15:54, Mike Everest via Public wrote:

To follow up, I went on site this week and enabled all LTE channels except for B28. The EP06-E would switch to B28 but no traffic would flow creating dramas. Now it seems to stick to B3+B3 and hasn't dropped out yet. There are a few B28 only towers around the farm including behind the dish that are closer than the B3 tower and there's probably been some dicky interactions. The antenna configuration on the LHG isn't really suited to 700MHz, methinks.
i have seen the sim card warp due to heat and cause dropouts. But that does not sound like your issue. B28 is often conjested with every tom, dick and harrys iphone trying to get something from a long way off... On Fri, 26 Jan 2024, 13:32 Jason Hecker via Public, < public@talk.mikrotik.com.au> wrote:
