2820, HG612, Sky Fibre and X-Kryptor was created by mbames
I have a 2820 running beta firmware (for DHCP options 60/61) so that it can authenticate with Sky via a HG612 modem (which is connected to WAN2). This configuration has worked very well ever since set it up (18+ months ago), and previously the 2820 worked perfectly with Sky LLU.

However, for work, we are forced to use the rubbish remote connectivity solution from Barron Mccann called X-Kryptor. I have noticed over the last 5 months that my X-K based connection will drop out (pinging a device at work times out for 5-10 pings), and then it generally recovers. Other devices on my home network seem to retain their access to the internet at the same time, so I don't believe that actual connection has a whole is dropping out. Prior to this, the XK solution seemed to be pretty stable.

Having complained repeatedly at work about this, I was given a second laptop (HP vs the original Dell). This also drops out, pretty much at the same time as my normal machine does (although sometimes one fails, and then the other fails a minute later or so).

"Work" are blaming the Vigor saying it must be doing some packet inspection, which is breaking XK. To try and test this theory, I reserved an IP address based on the MAC address for my normal laptop and then popped that into the DMZ. No difference. I have also turned off pretty much all data/pack inspection options I can find.

When working from home, it is generally ok in the mornings and get worse in the afternoon (working the other Bank Holiday Friday, the connection was perfect). I don't believe there are any capacity issues in the exchange/cabinet as everything else keeps working fine. I have tried uploading/download multiple GBs of data from work (generally ISO files), and it seems that "loading" my connection doesn't seem to have any affect.

Both machines were connected via a TP-Link Gig switch and that in turn to the Vigor (via a SamKnows Broadband monitoring unit). The main laptop is now hardwired direct to Vigor. I also see the same issues when connecting via WiFi.

This is really starting to hack me off. I could replace my router with another one, but that means shelling out a lot of cash to replace something which may or may not be faulty.

Does anyone have any ideas, or maybe someone from Draytek can come to my rescue? I have had numerous products over the years (2800x2, 2820x2, 120, AP-700). The basic 2800 seems to have died - all the NIC ports one by one stopped working, but otherwise things have been good (some other fault with the 2800vg was fixed under warranty).

Thanks,
Matt

No comments/thoughts? Not even from support :-(

In desperation I reverted back to the Sky Router this morning, and that just sat there with an unhappy yellow face. Guess I should be grateful I can connect at all!

Removed the SamKnows box, problem still exists.

Fired up a syslogger, and these messages did crop up (but not for every disconnection)

I find it rather odd as the MAC address quoted is the NIC, which is what I am connecting via rather than the wireless card (which is disabled by policy & by the switch on the laptop), however the WLAN_DBG suggests to me that the router believes it is doing something by wifi (unless someone just c**ked up the syslog message descriptions)

This resolved itself (apart from the 2820 syslog messages being wrong), work eventually admitted their XK boxes were poorly configured.
