Various questions about the 7800N
Posted: Tue Aug 16, 2011 8:10 pm
Hi all,
I've recently purchased a 7800N which I'm pleased with so far! A few questions I have:
I'm using an ISP in the UK connected via standard BT ADSL2+
Here's the information from the router:
DSP Firmware Version A2pB025f.d22k
DMT Status No Defect
Operational Mode ADSL2+
Upstream 446
Downstream 12552
SNR Margin(Upstream) 20.0
SNR Margin(Downstream) 12.3
Line Attenuation(Upstream) 11.2
Line Attenuation(Downstream) 21.0
1. I recently turned on PhyR, clicked on Apply and then Save Config (to the firmware). I used the Restart feature after that. When the router booted up it wouldn't sync up on the DSL at all. The DSL light was permanently off. On the web interface the DSP Firmware Version (on the ADSL status page) and the Hardware Version (on the advanced Status page) were both showing as unknown. I tried turning PhyR back off, no luck. I tried various restarts and even reloaded the firmware with the current settings - still no luck. It seemed the only way to fix the problem was to restore factory defaults. Strange indeed, perhaps a bug?
2. The system log is filled with messages like this:
daemon radvd[1392]: our AdvValidLifetime on br0 for 2a02:_____ doesn't agree with fe80::_____
daemon radvd[1392]: our AdvPreferredLifetime on br0 for 2a02:_____ doesn't agree with fe80::_____
Any way to stop these messages?
Is it possible to filter the system log to only show messages about the DSL connection?
Is it possible to see a report as to why the DSL resync'd during the night, what was the cause, etc?
3. How do I set the router domain name to "home" and the router's hostname to "gateway"? At the moment it's showing up as "gateway.home.gateway.home" which looks a bit strange
4. Is there any benefit turning PhyR on my connection? Does BT ADSL2+ support it? I have a relatively high SNR Ratio which might suggest noise on the line is a little variable. Is there any confirmation on the web interface that it's working?
5. How can I see which path mode the DSL is in? (FAST / INTERLEAVED)
6. Do you think I would benefit from setting the SNR margin manually? Do I need to restart the router when changing this value or it will resync automatically?
7. What is SRA in the ADSL Mode page (the Capability bit)? It's currently unticked
This is all that comes to mind, sorry for all the questions!
