My router works fine - as is evidenced by the fact that I am writing to you wirelessly on my computer.
There is nothing wrong with Apple router to do most internet activities..
NAT routers work easily from the inside.. ie as long as you need the service.. it will open the port for you.. it does not need any port forwarding or upnp or nat-pmp or anything else.
you are saying I should ditch the Apple router and but another one? I just want to be clear that I am understanding you.
I am recommending you buy a different brand router that support upnp.
You can keep the airport router and use it bridged to do wireless access point duties.
Please note I tried to say I am not able to directly make a recommendation.. I would be looking at forums where people who support tivo are active and will give recommendations for the best router.
Find out if people are using the Spectrum modem router in full router mode and it works fine with Tivo. If so that is one possibility.. depending on monthly charges.. which I also avoid like the plague.. but as internet systems become more complex may give you some greater source of technical help in that it is Spectrum's problem.. end to end.. even if they try and blame Tivo.. Once you introduce another brand of router.. they will wash their hands.. your internal network is of no concern to them.
Are you saying that with another router I can get rid of all the splitter, POE filter and bridge? My understanding is that this is a Spectrum issue and that I need these things... I may be wrong
If your spectrum modem router is fully bridged.. and the airport is the one and only router in your network.. this is NOT a spectrum issue. This is entirely a configuration setup problem with the airport. Once bridged the modem router becomes a dumb converter between mediums.. ie cable HFC to Ethernet.
I am not sure what all the different products you have are doing.. my understanding is this is because you are getting cable service for both TV and internet via the one service. You will need local help to figure that out.
If you get Pay TV via ethernet now.. none of it should be necessary. You simply connect everything by ethernet (or wireless if wiring is not possible). If the cable service still provides TV it is part of the total cable spectrum (hence the ISP name) and the splitter allows the use of both cable TV box and Internet box.
3. Before lightening struck, I had my previous TVs, TiVo Bolt and TiVi Mini all working well. Now that I have replaced them all, I can't get it working. I had a heck of a time previously getting everything set up in the past -- that's when I had to go buy the TiVo bridge, the POE filter and the splitters. They are all still in place. I have done nothing to them.
The problem is you need to do what you did in the past in terms of configuration to get airport router working.. and with all the replacements the settings could also be different.
Do Spectrum have a home installation service where you can employ a tech for a couple of hours.. ??
My standard way of fixing the internet is DIY.. but I send my car to the mechanic.
I could buy the manuals and tools and self service.. I used to do it.. when everything was simple and mechanical. Now the service centre plugs a computer into the car computer which tells them what needs fixing. I also am very allergic to grease, oil and dirt. Happy to pay a tech to do the job.. !! Get his hands dirty.
There is no reason you should be an expert car mechanic.. or network administrator.. get the person with training to do it.
