Netgear D6220 First Impressions
« on: February 04, 2018, 04:24:37 PM »

I've just picked up one of these from my favourite auction site and my initial impressions are pretty favourable.
It's only been running since yesterday, but so far:-

The good:
It's Broadcom based and supports G.INP.  :thumbs: Looks like it's a 63168. (thanks ejs for reminding my how to use 'cpuinfo' :-[)
Telnet was easy to open up so I can get line stats with xdslctl.
Line stats so far look decent on my circa 800m line. I'd say errors are looking a bit better than my Zyxel 8924.
Wireless performance seems pretty decent.

The not so good:
Some of the front panel LEDs are rather bright, but can be turned off in the GUI.
The GUI is the usual Netgear affair which isn't my favourite but works well enough.
Only very limited stats available in the GUI.

The darned right annoying:
Lots of what should be simple config changes trigger a full reboot to apply (eg adding a static DHCP assignment, or enabling IGMP Proxy). :rant:

/proc/cpuinfo cannot be run because it is not an executable file. What you type in to display its contents is
Code: [Select]
cat /proc/cpuinfo

A month on this is still performing very nicely.
Had some re-syncs but that's not unusual for this line.
For 17.49 (delivered) I think I did ok.
It's a keeper ;D

I too have no obtained one of these routers from my fave auction site.

I concur with tubaman about the annoying frequency of reboots when changing settings which in my view should not need a reboot and on most other routers do not do this, for example adding a fixed ip for a device on the lan!

It was a tad annoying getting the wan settings correct to get a connection, DSL was up OK but getting the net connection was just a little tricky as it has a habit of changing settings you have not messed with when saving.

Its only been up an hour or so and until I have 24 hours or so of data I wont know if it is better or worse than the VMG3925 I was using.

Stuart

Just to add the Shields Up reports all service ports as stealth, and the router does not respond to UPNP on the wan port either.

Hi Stuart,

I'll be interested to know how you get on with this.
With respect to the WAN setting I found it ok to configure but when you then go back to check the settings some of them seem to be random rubbish (eg ISP 'Adam'!). I assume this is a firmware bug as it actually works fine.

Mine is still working well and I have no plans to change it at present (unless another bargain comes along on Ebay  :-[).

I found mine was not on the latest firmware so updated it. So far it has been OK, slightly better SNRM than the ZyXEL but no change in speed as I'm capped. Too early to say what the error rates are like.

Been running now about 24 hours. Confirmed first impression that the SNRM is better than ZyXEL, been running around a reasonably stable 6.4 down and much less jitter than ZyXEL which was all over the shop varying from 6 down to 4.5 or so frequently. Noise in general is less as a result shows lower FEC rate and 2 ES down in 24 hours is not bad. I did make some changes to the layout of the LAN and power connections in that I now have a switch on LAN as well as I needed more than 4 wired connection. Power changes were to add surge protector plug on 4 way extension which now has router PSU in it. I now also put back a powerline on the LAN to make Wi-Fi better as it is very problematic in this house, as yet no increase in noise of error rate apparent from that. Obviously need to see how it fairs in week time as there has always been more noise around then.

Looks like we might just have found a modem that performs better than a Zyxel - on two lines at least. :o
It's a shame the GUI is not so comprehensive, and the issue with reboots after simple config changes would drive you mad if you were making regular tweaks (which I don't).

Now mine is set up and running I'm very pleased with the performance.
Only time will tell if it's going to be reliable.

One thing I have found is that the debug.htm page has been removed from the latest firmware however since I have not done a reset to factory settings it has not been disabled. The cfg file which is saved by the router cannot be edited as it stands but I am looking into that. There seems to be a program which can be run to enable telnet but as yet I have not had to try it. Over the reboot issue I dont normally need to change much so if I find anything for now I'll make a list and when I need to power cycle it for any reason I will make the changes during the 30 minutes I have it off for.

Stuart

I used the info/program from https://wiki.openwrt.org/toh/netgear/telnet.console to unlock telnet on my one. Worked a treat.
I do seem to have lost the debug.htm page as I think (I've slept since then ::)) I did factory reset it after the firmware upgrade.
