State of 3G/4G fallback on MikroTik?
by Karl Auer 01 Sep '21

01 Sep '21

We need to quote to a client for two routers capable of running a VPN between two sites - easy, that's a MikroTik. But they want a fallback to 3G/4G so that the site that falls back keeps Internet access AND so that the VPN keeps running. What's the state of MikroTik 3G/4G fallback? Last I looked it seemed very roll-your-own, and supported only a few very specific dongles... Ideally it would work like the (vastly more expensive) Merakis and just fail everything over to the secondary link if the primary fails, where "fail" would be either a ping test or interface down. That said, I'm OK with a solution that needs more work, as long as once done it is set-and-forget. Any pointers?

Updated Firmware for the Proscend 180T SFP VDSL2 Modems?
by Damien Gardner Jnr 08 Jun '21

08 Jun '21

Does anyone know if there is an Updated firmware available for the Metanoia/Proscend VDSL SFP's? There is a note from NBNCo relating to them being made unusable in the next three months due to incompatibility with new features being enabled on FTTN DSLAM ports. THe note seems to suggest by 'older' firmware that maybe there is a newer firmware available? Anyone know? Would be nice if I could keep using mine :) "A Metanoia SFP device with older firmware failed to negotiate synchronization at all once SOS and ROC was enabled on the DSLAM port. RSPs with services identified with these devices (approximately 700 network wide) will be notified to coordinate an update or replacement of these devices before network SOS/ROC deployment occurs."

Hi, Anyone using the GPER passive ethernet repeaters? As they aren't quite passive, we are interested in what the reliability of the units have been like? Our use-case will be for it to be installed in a building riser. Regards, Isaac

Chateau LTE drama
by Jason Hecker 08 May '21

08 May '21

Hi Any Chateau users here? I have one set up with 7.1b5, LTE firmware EG12EAPAR01A09M4G and the Optus SIM I discussed earlier. It's been working all week here in Ballarat with up to 3 CA's used and speedtests in the middle of the day exceeding 40Mbit. I sent it up to the client in Brisbane who is surrounded by Optus towers on all bands and it just wants to stick to B28 and UMTS with terrible speeds and lots of flapping. The B28 signals seem OK with an RSSI of -68. A cell scan doesn't show any of the other Optus cells except the ones with B28. No B1/3/7 etc. Can Optus selectively deny access to an IMEI on various channels? I updated the LTE firmware today to the latest and in the transition the client got a message that the SIM wasn't compatible with the service they were providing. A reboot fixed that though but the behaviour of sticking to B28 and UMTS was the same. I have disabled 3G and it's firmly stuck on B28. Any suggestions - need to get this running "normally" for Monday. Regards, Jason Hecker <https://www.upandrunningtech.com.au/> <https://www.upandrunningtech.com.au/>

Hi All, I need to build a CHR capable of >10Gbps routing performance (full BGP tables, no ip filters, no queues) Looking for what hardware platforms anyone has used (Lenovo, dell, etc..) what specifications (ram/cpu) with which hypervisor combination and what real-world performance has been achieved? Thanks,
