SRP527W Bonjour and Multicast

Post by Guest » Tue Aug 10, 2010 4:16 am


We have recently installed an SRP527W on our home and home office [10 computers - 6 of which are Apple] network, and have upgraded to the latest firmware:



Model:SRP527W, ADSL2+ AnnexA, 802.11n ETSI, 2FXS/1FXO
Version ID:V01
Hardware Version:4.0.0
Boot Version:1.1.17 (Jan 4 2010 - 21:15:46)
Firmware Version:1.01.11 (004) Jun 22 2010



It seems we are now (there was no problem with the Siemens router we were previously using) experiencing problems with Bonjour related applications (please note Im assuming Im correct that the symptoms point to a problem with Bonjour, but feel free to correct me if im wrong):

  • Bonjour printers are not detected (Apple OSX Server running Bonjour print server);
  • iTunes Remote on iPhone is slow to find iTunes servers (two media centers {mac minis} we have running), and thats if it can find them at all - sometimes it just sits there saying looking for library and does nothing;
  • Remote speakers connected via several different airport express (AirTunes / AirPlay) speakers keep dropping out and failing to reconnect - they then, of course, vanish from the iTunes GUI and also from the iTunes Remote GUI on the iPhone.



  • MacOSX Server with Bonjour Print Server running (among other services) - connected by ethernet to SRP
  • 12x wireless clients all on same SSID - 6 are macs incl. 2x mac mini media-center machines, 3 are airport express units with remote speakers connected, others are PCs.
  • IGMP v.2 enabled with proxy and immediate leave enabled.
  • Intervlan routing enabled
  • RIP disabled




As yet I have not found any solution to the printer problem.


As far as the speakers and remote go, cycling the wireless (airport) from on, to off and back to on, seems to enable iTunes to discover (rediscover) the Airport Express speakers again, and remote application on iPhones to discover iTunes on the media center computer that has just had the airport turned off and back on.


Problem is that this is happening every hour or so..and its become annoying! Ive read many other forums where people are experiencing similar problems, however it always seems to come back to a multicast issue...herein lies the problem - how to configure the SRP for Bonjour mulitcast?


I note Andrew Hickman states in another previous discussion on the SRP527W series, that Bonjour was not supported - that was back in June of this year (2010). He also said that it was on the road-map for a future release of the SRP5XX firmware (the firmware version in that discussion was 1.01.01 (006) Jan 22 2010, we e now up to 1.01.11...can I assume Bonjour is now supported?


My questions:

1.Is Bonjour and multicast supported yet?

     a) if so, what do we have to do to configure it for Bonjour?
           aa) From my reading I believe the issue Im experiencing is because of an issue with the way multicast is handled on the SRP that correct?

     b) if there is not yet any support for Bonjour, when will it be supported? Apple products networking features are so reliant on Bonjour, and there are SO many Apple devices that this issue seems crazy!



Any / all help is much appreciated! If youd like any further info on the setup, please let me know...just want to get this working as Ive been bashing my head on a brick wall for the last 4/5 days...reading forums, trying everything...with no luck yet.

Hi Vaughan

I have the same problem and I have spent hours with Cisco support even with Level 2 and 3 with no luck, they finally admitted that there is a fault in the router and they are offering me a full refund including the support contract. I suggest you ask them for a full refund and buy and alternate model until Cisco get there act together, I bought Draytek 2820vn it works like a dream from day one. when I first bought the SRP527 I though it I will have no problems and that will be supported by one of the best company in the world for networking however I was shocked to see the level of support I had to scream on the phone to try and get any where with them, Cisco have really let me down. I waited for more then a year to try and see if Cisco will release a fix but nothing yet. and every time I call them they say its on there road map. its been more then a year now, nothing has happened.

I was the first to notify cisco about the problem.


Kind Regards

Claude Toma

Hi Claude,

Thanks for the info on this... its been driving me crazy! For what seemed to be such a good router, Im severely disappointed by this! Its rediculous that the very foundation of Apples Networking, Bonjour Mulitcast, is not supported properly by one of, if not the, largest Network manufacturer in the world! I will contact Cisco and request an RMA and go buy something else... will post here what their response is like.


Thanks again for info on your experience.

Thanks for this information.


So the 527W does not support Bonjour


Telstra Australia [Australias Largest Telco] has recently [2011]  begun packaging the 527W as part of their small business ADSL2 broadband product and apparently knowingly providing these to MacOS environments.


Clearly this is setting many small businesses back a considerable amount of time and energy, not to mention money.


Unless I have missed a recent update/upgrade I am assuming as of today, Feb 10 2011, Bonjour is not supported? This being the case I will recommend to my client they ditch the 527W.


Anything I am missing?

Hi All,


Weve just fixed an issue related to this problem.  Could you please try MR3 (v1.1.19) and let us know if that fixes things for you?


This release will be posted to in the next day or so.  If you need a copy sooner, please send a mail to providing your user ID.  MR3 is now available at
