2.4 and 5g Telstra Smart Modem - can't choose

Answered

Hello All, my cable modem became faulty recently and was provided the new "Telstra Smart Modem" with the coax cable box. Gone from small to now 2 units one huge...? Anyway, the SSID doesn't distinguish between 2.4 and 5g so it's just fate which one your wifi chooses. Terrible idea, how do you change this as the settings won't allow you to, e.g. 2.4 settings can be changed, but the 5g just takes the same SSID name... just silly. How do you select the 5g wifi on this new "Telstra Smart Modem"? If the answer (I suspect) is 'you can't' then looks like gumtree to buy an old cable modem. cheers

Good on you, but band steering is not always bad...

Re: 2.4 and 5g Telstra Smart Modem - can't choose

thank you.
Interesting the old cable modem was around (true) 112Mbps most days, but never under 80Mbps - the exchange is in my street.
This new one (or 2 as it comes) is at best 70Mbps, but at this stage around 40-50Mbps, so i'm not exactly thrilled.

I'm trying to figure out the antenna connections (there are 2), I have a 5db antenna, but it doesn't seem to do much, but I only have tried it on one of the connectors. It would be good to see what the specs/schematics are for these 2 connectors.

Any idea, sensi' would be well received

Those two antennae sockets are for the 4G backup. Attaching an antennae to those sockets will not improve the WiFi. Have you tried doing speed test with device connected to a LAN port. If you have transferred to NBN ii might be the NBN connection limiting your speed. You can check the speed of the WiFi link by logging into the modem. On the basic home page if you hover over a device that is connected to the WiFi the WiFi link speed of that device is displayed.

 

If you are looking for information on the Smart Modem there is a link to a unofficial manual in this post..

Re: 2.4 and 5g Telstra Smart Modem - can't choose

Thanks heaps, because the antenna does nothing.
I'm on coax cable not NBN... that would be slower than my original 110Mbps and the other day we peaked at 122Mbps... just as a little bit of wow...
Anyway, I've check the setting speeds and it states higher speeds but just can't get them back to the old modem. Currently the laptop I'm using is stating 52Mbps, with a speedtest of 43Mbps.
I think the new modem doesn't have the transmission of the old one (in it's current place).

The old modem still works - Wifi only, but the Ethernet(s) got shot out by lighting recently. And this is why we needed a new router. was hoping for the same, but hey it is what it is.

Any suggestion other than moving the new box? thanks dave

You could turn of the netgear cable modem for 10-15 minutes or disconnect the coaxial cable for 5-10. This can change the frequencies your cable modem uses on the coaxial connection and increase speed if its not just alot of people using cable network in your area

yes thanks always a good option... I'll let you know thanks again for your genuine time mate.
Saturday night never a good time to test... but it 'normally' never changes.
Just then on 5g after unplugging and unscrewing the coax

Learning to read modem logs is something Im still learning. But I can read cable line stats to a moderate degree.

Please post your modem RF stats:

Re: 2.4 and 5g Telstra Smart Modem - can't choose

Thanks heaps for looking at this, I genuinely appreciate your time and energy. Can I give you some KUDOS somehow?

I did see (googling) that this continuous "Missing BP Configuration Setting TLV Type.." issue 'may' be a loose coax cable connector inside or a corroded connections (in the locked house box outside). We did have a past issue with the connector(?) in that box and it was changed and all slow issue disappeared - this was a completely different issue (several years ago). Maybe the lightening strike that knocked out the router Ethernet has damaged that connector/thing? (whatever is in that torx locked box).

I'll try a different coax inside to see if that makes a difference. "This Missing BP Configuration Setting TLV Type" is a bit interesting though.

Re: 2.4 and 5g Telstra Smart Modem - can't choose

I do this because I enjoy it, no Kudos needed 🙂

A different connection may make a difference. You could also connect your pc directly to the cable modem via ethernet and run a speed test from there.

Re: 2.4 and 5g Telstra Smart Modem - can't choose

Well let me say, you are a nice person, so thank you.

 

Silly me getting caught up with the techie stuff as we do, we overlook the simple stuff.  I have already got a pc connected directly from the beginning of this.  and yes it is doing exactly as before... 112Mbps which obviously eliminates the coax connections etc.  I stupidly overlooked this chatting here to ONLY focus on the wifi issue.  Sorry.

 

I think as I did originally that this new box doesn't have a better distribution signal as the last router.  The test when I'm on top of it is 117Mbps https://www.speedtest.net/result/7753206772

 

So it simply means the new box needs to be moved closer to the action of the house...

Interestingly my initial thought, I'm sorry for being a dill and getting caught up with a false chase.  But one thing we can draw from this is that the old

C6300BD-Telstra https://www.netgear.com/service-providers/products/cable/gateways/C6300BD-Telstra.aspx#tab-features

has a better wifi transmission than the new gateway.

Any last thoughts? cheers dave

Re: 2.4 and 5g Telstra Smart Modem - can't choose

It could be the lap top having and older WiFi adapter works better with the old modem. I have both the Smart Modem and the Telstra Gateway Max and have run several tests comparing the WiFi signals from both modems using several different measuring devices.

Measuring the WiFi signal using a WiFi analyzer app the 2.4Ghz band on the Gateway max is about 1 dbm stronger at 30 Meters. The 5Ghz band on the Smart modem is about 1 dbm stronger at 30 meters. The signal strength varied greatly depending between different measuring device used

A speed test at 20 meters both modems had roughly the same speed at 20 meters on both the modems and both the 2.4 GHz and 5 GHz band. It did vary slightly depending on the test device.

At 30 meters the 5 GHz speed was 13 Mbps faster on the Smart modem. 33.6/11.6 versus 20.8/6.71. On thee 2.4 GHz band the Smart modem was 5 Mbps faster. 33.9/10.6 versus 27.6/8.89. There was a huge difference between devices at this distance. One device could not failed the speed test on the 5 GHz band on the Gateway Max.

One thing you could check is that the power is set to maximum on the modem.

Hi All, update.

I tried a few things, after all your kind help.

Power is at 100%.

 

I hit defaults on the settings, even though the only change I made was "band steering".

Well I'm now getting a nice 72+Mbps (on 2.4), which is better than before.  As suggested by you above.  Interesting, with "band steering" disabled, 2.4 was pretty bad at 17Mbps.

So I'm not sure what really happened, but am grateful to you all for helping me work out this 1st world issue.

 

I hope this thread helps others to.

Thanks again for your time and energy... you are worthy of some KUDOS, cheers Dave
