[Bug 1310335] Re: IPv6 renewal causes network-manager to disconnect & reconnect

 

Still present today in a fully updated Linux Mint MATE 17.1. The router's page now displays a slightly different description for the offending part of its configuration: 
LAN Setup:
Router's IPv6 Address On LAN: [IPv6 address/64]
IP Address Assignment:
- Use DHCP Server
- Auto Config
Use This Interface ID: [ ] [ ] [ ] [ ]

Title:
  IPv6 renewal causes network-manager to disconnect & reconnect

Status in The Linux Mint Distribution:
  New
Status in network-manager package in Ubuntu:
  New

Bug description:
  IPv6 renewal causes network manager to disconnect & reconnect

  Happens *roughly* every ten minutes.
  My network is running fully dual stack.
  The problematic option in the IPv6 part of the router's settings is
  "IP Address Assignment"
  - Use DHCP Server
  - Auto Config    <---- Problem presents itself only when using this one
  I have a Netgear DGND3700v2 router, firmware version V1.1.00.15_1.00.15 (latest).

  There are 3 different PCs on WiFi and ethernet.
  Network manager settings are: one PC static IPv4, two DHCPv4 and all of them Automatic for IPv6.
  Linux Mint: 
  kernel 3.2.0-60 x86 network-manager version 0.9.4.0-0ubuntu4.3 (MATE)
  kernel 3.5.0-48 x64 network-manager version 0.9.6.0-0ubuntu7 (Cinnamon)
  kernel 3.11.0-12 x64 network-manager version 0.9.8.0-0ubuntu22 (MATE)

  Wifi disconnection log (repeated, ethernet reconnects seem to leave no trace and seem to happen slightly less frequently):
