A little transparency here would go a LONG way. I'll sit back and wait a while if I know Tivo is aware of the issue and is trying to correct it. But all evidence I have so far says they are NOT. They are blaming my network 100% and totally ignoring the possibility that it is on their end.
I couldn't agree more. You have to be proactive in situations like this. I understand that a C133 error could be an issue on the customers end. However, when multiple people are reporting the same error at around the same time, you have to take a look at your infrastructure and communicate any infrastructure issues to your front line support teams so they aren't wasting time troubleshooting C133 errors when there is a known issue. The amount of time wasted on both ends is absolutely ridiculous. Put a flippin banner up when customers go to login or even a automated message advising that there is an issue when customers call in.
I run a network operations department for financial institutions and I still find it hard to believe how many C133 errors I have come across on my Tivo box. With today's technology and data center redundancy, Tivo is either behind in their infrastructure, or this is a Q&A process issue when updating servers.
Routers that do NAT routing have to keep tables of active connections so they can figure out what goes where. It is quite common for router software to have bugs (Gasp!) that get it confused with lots of connections causing memory leaks and wot-not. That could easily explain rebooting the router fixing things. You could check and see if the router has newer firmware available (but sometimes trying to update firmware just makes things worse
All routers NAT otherwise it's simply a switch. If you have that many active connections that your NAT table gets overloaded then you will have issues with all other devices on your network.
My Troubleshooting Steps;
Can everything else connect? If yes go to Tivocommunity.com and see if the first post is related to c133. If there is, don't waste your time with support and wait for Tivo to fix their system.
Go to network Diagnostics ( Settings > Network > Network Diagnostics)
Verify that TCP/DNS Tests Succeeded. Select Test Internet Connection Verify the test passed.
If the above fails;
Disconnect your modem and router.
Reconnect your modem and wait until it's offline. Once the modem is online connect your router. Run the tests again. If this still fails and you verified your internet connection is indeed active reboot your Tivo and run the tests again. If this continues to fail verify layer 1 (cabling). I realize this should be checked first but in home network not much changes constantly like in a datacenter. You will probably know if you moved your router and disconnected cables (or someone should know). ;-)
*side note* I hate rebooting my Tivo, waiting for it to load seems like an eternity. .
