To add to the pot ... We have MANY installations of the 8817 and RB450/G RB2011 RB751 RB951 and have no issues with the hardware or combination. On 27 October 2014 13:23, Ben Jackson <ben@elogik.net> wrote:
Thanks Matt, yes I always make sure the modem is set to pure bridge mode with nothing "surplus to requirements" switched on. The Draytek vigor 120 will automatically disable DHCP when bridge mode is enabled, the TP-Links I’ve used don’t and require you to to flick another switch.
Alas, this doesn’t solve the issues I’ve seen! :(

Hi Ben, regarding point two, ensure the dhcp server on the modem is turned off when in bridge mode or this type of problem may occur.
Regarding instability of MikroTik pppoe, any issues I have had have been related to other things, mostly ADSL noise. As far as I am concerned, there is nothing more stable than tplink 8817 and mikrotik. For these sites.

Hi all,
Two questions:
1) Any idea why a routerboard which has not had an admin password assigned to it would suddenly not accept the blank password and give a “incorrect password” error through winbox? Firewall rules were in place to only allow ip addressed from the internal LAN to connect so I’m pretty sure they weren’t hacked and the password changed.
2) ADSL and MikroTik - the ongoing saga. I was following with much interest the recent thread started by Mike about which ADSL modem to use. Seems the TP-Link 8817 is the one to go for, however I have tried this modem in various installs and have still has intermittent slowness and just plain weird packet loss / latency.
When I use MikroTik’s as a simple DHCP client in conjunction with a cable modem everything seems fine, which means there is something amiss with the PPPoE dialler? I have tried messing with MTU settings in various places, but I really can’t see MTU misconfiguration accounting for a loss of 8-10Mbps at times?
I have had so many problems with residential ADSL performance with MikroTik routers I am unfortunately now looking for alternatives to MikroTik. Configurations I have tried:
- Bridging various brands of modem, setting up PPPoE client on gateway interface of MikroTik. Performance using this method (in my experience) is terribly inconsistent and sometimes just downright awful. Modem sync speed is normally fine, download speeds are inconsistent and often very poor. ISP reckons they can see “authentication dropouts” from the PPPoE client.
- Using the modem as a router and routing between the two (192.168.x.x) subnets using the MikroTik. This leads to double NAT issues, although strangely performance seems more consistent than option 1.
- Using the MikroTik as a simple layer 2 bridge / switch which is assigned a static IP in the DHCP range assigned to the gateway (have also tried DHCP). This seems to give the best performance but it seems to obviate buying a MikroTik when it is not even being used as a router. Also means that I have to rely on the (often inferior) feature set of the modem to manage the network.
It seems to me (and I don’t really have any hard evidence to back this up, just experience) that the PPPoE client on the MikroTik is rather unstable compared to those running on the various modems I have tried, and any noise / glitches on the line will cause it to misbehave.
So, anyone have any suggestions on alternate configurations (static routes?)
Thoughts?
Ben
