Failed access to a single website - modem/router troubleshooting guide

summary of issue - on or about 17 Dec 2020 I could not longer access the www.tsp.gov website from any device that was using my home network wifi (desktop, iphone, ipad) via chrome, edge or avast .  I could access the site from my phone if I turned off wifi. I had not made any changes to my modem or router and only that website was an issue. I was able to access all other websites 

following is a recap of how I resolved the issue (windows 10, spectrum cable modem, c2300 router)

1st I had to figure out where to start.  Assumed it was either website, router or ISP.  As this is a popular website and no tweets or posts about any issues on the web I decided to start with my router (TP LINK).  

TP Link reps (on a saturday) were very responsive and helped me confirm it was in fact a router issue.  This was determined by bypassing the router and connecting my desktop directly to the cable modem via ethernet.  In this configuration I could access the site. things they had me try that did not work

- change to google DNS 8.8.8.8, 8.8.4.4

- change MTU to 1400 (from 1500)

after 2 hours they were unable to resolve beyond that so plan was to escalate on monday.

I was impatient so decided to troubleshoot on my own now that i knew it was a router issue.

i connected an old linksys router to the cable modem and was able to connect with the website.

when i connected my tplink router and restored the settings from a saved file it would not work

the following worked (need to be patient for each step to complete as it can take a couple of minutes - each)

- power off both cable modem and router for at least a minute

- power on the cable modem and wait until is settles

- connect router and power on.

- hard reset of router (press and hold reset for 10 seconds)

- soft reset of cable modem (need to wait until router settles). took about 2 minutes for the internet light on router to turn from orange (no connection) to white (connection)

- log into router 

-do a fresh set up.  it did not work when i restored from saved configuration file

- i used clone MAC address 

I still have no idea about the root cause of not being able to access only the one website. 

Heater / AC Control Panel Plate - Mazda (NA01-61-C04A) replacement

 plenty of how to videos on google so just adding couple of thoughts 

amazon $32 w/ free shipping

mine was in bad shape after 29 years.  

the control knobs are held in by small phillips head screws.  i had to remove my after market radio to get at the lower two screws.  i used craftsman ph 0 x 40mm screwdriver. think about where the screw would wind up if it drops.  recommend using a towel, 

use old tooth brush to clean out the grooves

there is a clear plastic piece that comes out when you remove the old decal for fan settings.  i used goof off to clean it up.  it appears to be a light diffuser.

Miata NA radiator replacement

videos available on youtube so just highlighting a few specifics that would have helped me

i got a standard one from o'reilly's locally as did not want to wait for amazon or ebay.   $117.  probably could have saved $50 if bought on line.

original radiator lasted 16 years (165K miles), replacement 13 years. (70K miles)

i was able to re use the fans, grommets and stop bolts.  came with the 8 metal clips that thread the bolts for the two fans.  i did need to replace the bolts as they were rusted (metric size 6 20mm) from hardware store.

removal and replacement was straight forward and can be done alone.  was able to access all the bolts to remove the plastic bottom guard shield and radiator by just jacking up the driver side.  i did wind up having to jack up the passenger side when reinstalling the plastic guard as turned out a couple of bolts were missing.

removing connector on passenger side fan.  insert small flat head screw driver underneath tab  in center to remove

i was able to reuse.  needed to sand the rust off in order to fit the bolt thru the opening of the new radiator










you need to re use the grommets.  remove the center metal piece that allows you to squeeze them in and out
