G.INP question

Sorry for the ignorance here, but how do I find out if G.INP is supported by my cabinet (SMKBN cab 2)? And will it work with a HH5A or would I need to get a different modem/router?

Your cabinet is a Huawei so G.INP is available but your HH5A doesn't support G.INP. I recommend you get a Huawei HG612 v3B and unlock it with the B030SP08 firmware. You can then plug this into the HH5A and get G.INP

Thanks BatBoy. Will this be worth it i.e will I get a speed increase?

I went from 77 Meg to 80 Meg when G.INP was switched on.

OK sounds worthwile. So if I get a HG modem, how do I plug it into the HH5? just via ethernet to a port on the HH5? I don't really like the HH5, the wifi is [censored], so would consider changing that...

Yes, LAN1 on the HG612 to the red WAN port on the HH5. I find the wireless really good on my HH5A, but if you don't like the HH5 anyway, you could replace it.

It's not true that the HH5A doesn't support g.inp with one proviso, it's downstream only. I have one, and it does, and have tried both an A & B (don't ask why I have both - to do with moving and currently having two properties). Both give similar downstream speeds and rock-solid connections (about 56mbps on an 80mbps service). The B does give about 1mbps more upstream though.

When g.inp was enabled on my local (Huwai) cabinet, the change was very noticeable as prior to that I'd average one disconnect a day (now its only on the fortnightly scheduled modem reboot - and the B does the same thing). However, the first sign had been an increase in sync speed followed, within a day, with a reconnect with interleaving turned on (which lost a lot of speed) and then, about a week later a resync with interleaving turned off and the return of the lost speed.

The g.inp situation is a lot more complex that HH5A doesn't support it.

In reply to a post by TheEulerID:

Err I don't understand, these two statements seem to be contradictory.

Frm what I'd heard the latter was true? Hence the reason to get another modem...

The HH5A definitely doesn't support G.INP.

I had G.INP enabled and i'm using a Billion 8800NL and used this article here: http://www.increasebroadbandspeed.co.uk/g.inp

to determine that it had been switched on although my INP/DMT value is 47 and not 48 but interleaving is switched on at 8 on the downstream and 1 on the upstream. and i got a 3mbps increase.

Does anyone know if the bandwidth will increase further?
