DrStrangelove:

What does the logging on your DGN3500 say?

I can't seem to find anything overly useful in terms of logging. It logs security errors, but nothing that would help isolate this problem.

Had a look at the DSL line stats? Even Ethernet line stats.
Seeing any CRC errors? i.e. more than say 50 a day.

Here's the router stats:

What's the CPU/memory usage like?

Not sure how I'd query that information. I can't see anything obvious in the admin interface.

I'm just thinking out loud, as I like to know a bit about why something breaks before I go off and get something else.

Yeah, thats a valid approach. But sometimes its just easier to concede defeat and attempt to purchase a more robust product.

To be honest, I would have thought the number of devices you have would work OK with the current DGN3500.

I know Netgear halted the release of one of their newer routers to re-release it with more memory and I'm not sure what an olde worlde DGN3500 has inside it. But really how much memory could a LAN and a ARP table need, considering interfaces have their own buffering/windowing resources.

I did perform a firmware upgrade just the other side of Christmas. Its not impossible that this is the true cause of the increased instability since Annual Present Day, and that the increased number of wireless connections is just a red herring.

Hmmm... I hear what you're saying.

I see the latest Firmware Version 1.1.0.33(WW)

I checked the User Manual and there is an indication it supports SNMP, but that might be a road less travelled when looking for interface counters.

I'm assuming you have RIP disabled and using static routing. Using static addressing saves memory as you don't have routing tables. You just have ARP tables which in your case would be no larger than approx 10 entries.

I'd also have a look at the IP addressing.

I'd use IP network 10.nnn.1.0 255.255.255.0 for your LAN where nnn = your street number (1 - 254) ... or some such thing.

The reason I say that is if you have RIP enabled and use default IP addressing... well it's a recipe for disaster.

DHCP does help out here, but it doesn't stop static IP address conflicts.

I'd assign the Apple TV, TiVo, and PS3 and etc static IP addresses (if configurable) in the range 10.nnn.1.[10 - 20].
I'd probably assign static addresses to any devices on an Ethernet LAN.

You ADSL(WAN) interface just becomes your default gateway.

Also, I tend to use(that's just me) 'static' DHCP such that MAC are bound to IP as this is quite manageable on a 10 -20 device network.

Manage your LAN, don't let it manage you.... :-)

I'd be VERY interested in what your ADSL2 interface is doing regarding a stable interface.

Maybe easier to buy an ADSL2 modem (Vigor 120/TP-link TD-8840 with half bridge and IPv6) and a 'good' Gigabit router.

Oh, and your line attenuation indicates you're in a VDSL area, so you 'should' be getting a good broadband speed even above what is indicated. You could be like me though and looking at the house next door and thinking... what if.
As I'm right on the edge of an exchange network.

On an exchange network a Thomson TG585 will sync at 20 - 22Mbps as an example and give a speedtest 'indication' of 18Mbps.

Thanks for all your help there, Doctor.

We're right in the midst of "tidying up house to sell for maximum profit", but I may look at implementing your config suggestions once the dust settles. I must admit I currently use dynamically assigned IP addresses for all devices ATM, and use the 192.168.0.* range.

get one of these and that'll fix your issue - i had a similar problem and havent had a disconnection issue since.http://einfo.co.nz/shop/tplink-tdw8960n-wireless-300m-adsl2-p-17497.html?osCsid=a22c43d6bd8dbabc6a473223811bfd5d
