Same situation here in the US. DIR-857 keeps dropping internet connections. Sometimes it works and sometimes it doesn't. I have too many devices to reserve each IP. Tried most of the configuration settings and problem still exists. DLink needs to fix its DHCP issue on this device. Please post a firmware fix ASAP. I am a network engineer and have been struggling with this device since the 1st day it was released.

Welcome! (http://forums.dlink.com/index.php?topic=41537.0)
- What Hardware version is your router? Look at sticker under router.
- Link>What Firmware (http://forums.dlink.com/index.php?topic=47512.0) version is currently loaded? Found on the routers web page under status.
- Are you wired or wireless connected to the router?
- Was a Factory Reset performed before and after any firmware updates then set up from scratch?
- Was the router working before any firmware updates?
Internet Service Provider and Modem Configurations
- What ISP Service do you have? Cable or DSL?
- What ISP Modem Mfr. and model # do you have?
- What ISP Modem service link speeds UP and Down do you have?
- For DSL/PPPoE connections on the router, ensure that "Always ON" option is enabled.
Router and Wired Configurations
Some things to try: - Log into the routers web page at 192.168.0.1. Use IE, Opera or FF to manage the router.
- Turn off ALL QoS (http://vonage.nmhoy.net/qos.html) or Disable Traffic Shaping (DIR only) GameFuel (DGL only and if ON.) options, Advanced/QoS (http://en.wikipedia.org/wiki/Quality_of_service) or Gamefuel.
- Turn off Advanced DNS Services if you have this option under Setup/Internet/Manual or under Setup/PARENTAL CONTROL/Set to>None: Static IP or Obtain Automatically From ISP.
- Enable Use Unicasting (compatibility for some ISP DHCP Servers) under Setup/Internet/Manual.
- Turn on DNS Relay under Setup/Networking. Link>Finding Faster DNS Addresses using Name Bench (http://forums.dlink.com/index.php?topic=53222.0)
- Setup DHCP reserved IP addresses for all devices ON the router. Setup/Networking. This ensures each devices gets its own IP address when turned on and connected, eliminates IP address conflicts and helps in troubleshooting.
- Ensure devices are set to auto obtain an IP address.
- If IPv6 (http://en.wikipedia.org/wiki/Ipv6) is an option on the router, select Local Connection Only or Disable IPv6 options under Setup/IPv6.
- Set Firewall settings to Endpoint Independent for TCP and UDP under Advanced/Firewall. Enable or Disable SPI (http://en.wikipedia.org/wiki/SPI) to test.
- Enable uPnP (http://en.wikipedia.org/wiki/Upnp) and Multi-cast Streaming (http://en.wikipedia.org/wiki/Multicast) under Advanced/Networking. Disable uPnP for testing Port Forwarding rules. Enable IPv6 Multi-cast Streaming for routers that have a Media Server option. Disable IPv6 Multi-cast Streaming if IPv6 or Media Server is not being used.
- Turn off WISH, and WPS under Advanced.
- WAN Port Speed set to Auto or specific speed? Some newer ISP modems support 1000Mb so manually setting to Gb speeds can be supported by the router. Advanced/Advanced Networking/WAN Port Speed
- Set current Time Zone, Date and Time. Use an NTP Server (http://forums.dlink.com/index.php?topic=48695.0) feature. Tools/Time.
- Check cable between Modem and Router, swap out to be sure. Link> Cat6 is recommended. (http://en.wikipedia.org/wiki/CAT6)
How many devices do you have? Granted I have about 15-20, not all online at the same time. All might devices have reserved IPs and have never experienced this internet connections.
