I don't want to be rude but you replied as assuming I was a complete idiot that didn't know what i was talking about.
In my opinion it was obvious to anyone who understand the topic and doesn't assume that I have no idea, but sure, I could be wrong.
I don't get why you say that my Modem doesn't support that network, I told you I connected with it so it DOES support it. The issue is with the performance of it. No hard feeling intended, I just want to know if there's an issue with configuration of this is the best I can get.
I'm going to explain it all again, this time, hopefully, not leaving anything out.
The fiber to cabinet (FTTC or FTTCab) get to the modem as VDSL2.
The D7800 support VDSL, you can see it from it's specs: http://www.downloads.netgear.com/files/GDC/datasheet/en/D7800.pdf
If the modem didn't, as you said in the last post, I wouldn't even be able to connect. Instead, as you can see from what i shared, it DO connect.
The problem is that bandwidth sucks.
In more details:
FTTCab: Fiber get to the cabinet in front of the street, from there it is converted into VSDL using the traditional copper cable that reach my home with a standard phone connector (RJ11) carrying the VSDL signal.
That RJ11 is plugged into the modem VSDL input (Either the D7800 or the one provided by my ISP) and configured to connect (password VSDL ID etc..).
My computer connect to the modem/router via Ethernet Cable (or WiFi, but i tested all with cable cause the WiFi is expected to be slower then 100MBit).
If I use the D7800 as modem / router i get below 10 MBit download and well below 1 MBit upload. (ISP Modem is shut down in this configuration and not used at all)
If I use the modem / router provided by my ISP I get almost 100 / 20 MBit Down/Up (as it should). (D7800 is shut down in this configuration and not used at all)
My ISP specify that for a modem to work with their VSDL it has to support at least 8b and 17a profile, which the D7800 supports. But they suggest the 35b profile, which the D7800 is powerful enough to handle but currently doesn't support.
The 8b profile support at most 50 MBit download and 16 MBit upload.
The 17a profile support at most 100 MBit download and 50 MBit upload.
The 35b profile support at most 300 MBit download and 100 MBit upload.
So the 17a profile supported by the D7800 should, theoretically, be enough to support my network but it doesn't even come close to it.
This can mean either of these things:
- The D7800 sucks and I won't be able to use it to get proper network speed, ever
- The D7800 is not well configured, and I was hoping to get suggestions / advices on the matter
- My D7800 has some hardware issue
The ISP provided modem / router is not bad at all, but it doesn't support QoS and the WiFi signal is weaker and can't cover as well all the house. So if I could make the D7800 come close to the performance my network is capable off I'd prefer using it.
My ISP Provider is TIM Italy. The offer is called Tim Connect Gold Fiber.
I posted in this community to:
- know if someone else had similar issues
- know if someone reach VSDL of 100MBit/20Mbit (Down/Up) with this router
- obtain advices or potential configurations that could help
I really hope I now breaked all the things down without leaving anything for "obvious" and I'll get some feedback.
