New 5G Home Broadband - Upload speed query

[craigs85]

Hi everyone.

New customer on the 5G Home Broadband service here, just wanting to ask a few questions.

I was amazed when the website told me I could get 5G in my area, so had to give it a try. Currently coming to the end of my Plusnet landline broadband, and don't want to commit to 18 months or more as FTTP is meant to be available soon, so thought I would try Three's offering.

I am blown away by the download speed. 300mbps+ some times.

However, the upload speeds are more worrying and possibly the deal breaker for me.

Sometimes I get a 4 or 5mbps upload speed, which compares to what I get down the landline with plusnet (but i only get 27mbps download on the land line, as opposed to 300mbps+ at the best times on three).

Throughout the day though, the upload speed drops to less than 2, which gives me some issues.

I have just now ran a speed test and here are the results, and the info from the Cellular page of the Hub iself.

Speedtest: The download was 280, upload was 1.79.

Cellular Tab: 

• Access Technology - NR5G-NSA
• Band - B1,B3,n78,n78
• RSSI - -96
• Cell ID - 815689
• Physical Cell ID - 238
• UL Bandwidth (MHz) - 10M,100M
• DL Bandwidth (MHz) - 10M,15M,100M,30M
• RFCN - 99,1392,640548,632666
• RSRP - -110
• RSRQ - -14
• SINR - -3
• RSRP-NSA - -99
• RSRQ-NSA - -2
• SINR-NSA - 17
• TAC - 2102

I have moved it to an upstairs window sill that I think gives the best placement. Would I benefit from an external antenna? The thing that puzzles me is that I can get 5mbps upload speed at certain times, so I think the placement is ok..

Any suggestions would be appreciated.
Thanks,
Craig

This one is crap as I try that as 5G hardly picking up!

The new version shoould be lots better with higher gain! New 3400MHz-3800MHz, 5G band with 11dBi gain

Cheers for that. It's an expensive experiment isn't 😥.

Would i not need 4x4 mimo? That one is 2x2 isn't it?

May just give up and go back to land line.

Appreciate your replies

Is it worth tinkering with any of the settings on the hub itself?

Such as Access Technology on the Cellular Band setting tab. Currently its set to 'NR5G-NSA/4G (Auto Switch)'.

Would a different option in here make a difference (positive one! 🙂 )

[bulldog555]

You have to remember 5G only work with 4G alongside it because Three use NR5G-NSA (none stand alone) at present time mean have to use both 4G and 5G to get 5G working properly.

[martcoug1]

The issue is, you need a good 4g signal too, it uses this for upload unless you can cell lock... Three 5g uses NSA not SA... yet

[craigs85]

Ah, so upload uses 4G, of which I do have a much weaker signal.

How do I cell lock so it uses 5G?

[bulldog555]

There is no cell lock on this router sadly with current firmware B12

How did you pull out cellular tab?

[craigs85]

Think I just copy and pasted it from the hub login, why?

[craigs85]

Appreciate the replies everyone.

Regarding Plusnet/BT, FTTP isn't available in my area yet. Only FTTC which I currently have (although its coming to an end in 30 days). They won't offer rolling monthly contracts (unless I pay double the price), hence me trying this as an alternative.

In the exact same spot, sometimes I get up to 5 download, which will be fine for me. But other times, I get less than 2 which does cause an issue. So I don't think its entirely down to the location of the hub, as that hasn't moved.

Does the upload get throtted at certain times?

I'll still have a walk around with the hub and see where I get the best results. So lower RSRP = better, and lower SINR = better?

I could sacrifice some download speed for a bit better upload if this is possible 🙂
