It was a dark and stormy...late afternoon...yesterday, and....
I had started out almost 7 years ago with a Siemens 4100 DSL Modem, which worked the way I needed it to for my home network. And, wasn't sure how easy it would be to find another like it. I was running it in the cross between router and bridge mode...so that my router could maintain my dyndns info (though it wasn't too long after that I moved that to ddclient on box, which has been more reliable...but I was having ddclient scrape from the router, though the ddclient for the router on my Cox connection wasn't supported so that uses checkip.dyndns.org. So, now both do.
Would probably be too much work to make ddclient go out on the right IP so that ip route will send it to the DSL router, so it can query the DSL modem for what the real external IP is. Though the new cbox/dbox setup would simplify things....but the migration has stalled as I've been working on getting cacti moved from box...and it hasn't been going well. Lots of old templates and such don't work on the new, so I've been reworking what I feel I can't live without....
That includes the graphs of my DSL modem stats....
Anyways....when the Siemens 4100 started dropping the connection a lot (around the 3 year mark) and changing the filter didn't help, I had heard that these things wear out... So, I tracked down a new Siemens 4100 on eBay...and switched to that....and that got things working again.... Then a couple years ago, things go bad consistently....though I could see from my cacti graphs that SNR drops in the evening. Though I wasn't able to get local service to restore/fix things. I tried the AT&T forum on dslreports.com, and they changed me to Interleaved, which helped....
But, I had started shopping around for a new DSL modem.... somewhere in my journey's I acquired a Zoom ADSL X3 5760 Modem. But, since things were working...I put it aside as my spare for when things stop. Seems I've had it so long that its no longer available....got it July 9, 2012 according to Amazon.com
For a while now, it would drop the connection now and then during the week (between its weekly self-reboot)...at first I suspected the router, since its twin had gone away in much the same way several months earlier. Though the router do also have failsafe configured, so if it can't talk (ping) to box or the WAN gateway...it reboots. Though at some point AT&T made their gateways unpingable. So, it was pinging google.
But, on April 6 it got really bad....my IRC connection was resetting practically constantly. Though since I had swapped the router before, and swapped it again. Though maybe now I wonder if its watchdog was too aggressive. Things were usable, but the line drops would be annoying. Also the IP staying the same through drops didn't make me question the DSL modem.
But, then on April 13, things start getting really bad....and I was getting 50+ messages a day from ddclient that my IP changed. It seemed to stablize a bit on Monday....though it was still dropping regular enough that I switched to using Cox for my IRC screen session. Was going to defer to the weekend to make the swap.
Well, yesterday the weather was bad...lots of lightning, rain....and I first display I looked at when I got home said "NO INTERNET". Though it was probably a temporary outage, because it did appear to eventually come back while I was working on unboxing my 'new' DSL modem. And, try to figure out how to set it up without the Windows wizard it provides or the lack of documentation with it...there was a small CD, which didn't really provide much depth....but I found what IP it would be and that it has web interface....it also has a telnet interface and an FTP interface.
Anyways...it turned out to be pretty straight forward getting it working...the hard part was figuring out what the non-default options meant, and whether I would want them.... the main one I turned on was "fullcone NAT". And, I set my router in with a reserved IP and made it DMZ host, so I can keep all my forwards there...plus the Zoom is limited to 16, which isn't enough .... though this may change when I make use of its DMZ feature as well (doing reverse proxy on cbox/dbox to everywhere else on my home network...running firewall on these boxes already, to implement policy based routing.) And, enabling ICMP on the WAN interface (its also possible to enable http, ftp and telnet on the WAN interface as well.)
Getting it working in Cacti again, turned out to be much harder.

For quite some time, I've been running WRT54GS routers....that I had hacked to run Sveasoft Alchemy...eventually reaching 1.0 release and then pretty much doing very little to.
Originally, I had gotten a WRT54GS v1.1 that I upgraded, and used with my Roadrunner Cablemodem service. Later word came out that newer WRT54GS had less memory than before, and were switching to non-replaceable OSs. So, I started keeping an eye out for older WRT54GS routers...to get as a spare. One day in a Wal-Mart, I was going through the WRT54GS's on a shelf...when way at the back behind the newer v5 stock, was a v2.0. Well, I had to buy it right then and there.
Later when I moved to Manhattan, KS...I was presented with the opportunity to go dual WAN. Well, wasn't my intent, but I was forced into it. So, not wanting to mess up my 'cable' configs. I set up the backup WRT54GS for DSL use.
And, things have been humming along pretty well, with the two WRT54GS routers and the running of both Cox and AT&T broadband.
That was until last September....I was trying transparent proxy and ended up bricking the WRT54GS for DSL. So, I started looking online for a new router to replace the WRT54GS that would be better than what I had now. One of the key features of Sveasoft is the better QoS...which was important since I was doing a lot of VoIP (having at the time both Lingo and Vonage, since neither had Manhattan, KS numbers...they have since gone away...and its just Broadvoice now. But, I've been thinking of getting another....) But, I had turned of QoS on the cable one, because I found that it was affecting my ability to see the speed improvements that Cox had been making to it. So, I had already started looking at what next after WRT54GS....but now with a bricked router, things were more urgent.
So, what I did was order a pair of Buffalo WHR-HP-GN (with dd-wrt) routers from Amazon, using Amazon Prime...on September 9, 2010.

So, yesterday afternoon...there was quite the thunderstorm.
I could see that the power was flickering at home, VNC'd to 'gumby'. After a while...it was steady on battery. I went over to 'tardis', and watched the UPS run down and cause it to hibernate. Didn't stay to watch 'gumby', headed in to the hallway to visit with evacuees and then go up to watch the storm....and then see about going home.
As I was leaving I saw that my connection to home had gone away. I couldn't remember if I was going into my home network via DSL or Cox. Though based on available data, looks like it was DSL. Will confirm on Monday.
