Hi,

I have a RBI Connection with Vodafone that we have had for a few years. When originally installed it delivered around 30Mbps. Over time this dropped to less than 10Mbps.

After raising the issue with Vodafone, I ended up getting a new Modem (a Huawei B525s) and new, dual Antennas setup in a MIMO configuration.

When this new configuration was installed, I had peak speeds of over 100Mpbs, with typical speeds of 70Mbps.

This lasted for approximately a week. After which time, the maximum speed is back down to 30Mbps. When I raised it with Vodafone I was told that the higher speed was achieved when connecting to a more powerful cell tower that was further away, but less reliable and now, I was connected to a "less powerful" but more reliable, closer connection. Not sure if this is correct or not, but regardless I haven't been able to get back to the original speeds of 70Mbps.

Is there a way around this? Do I need to adjust the positioning of my antennae to pick up the faster cell tower?

During the week that it ran at 70Mbps, I have no issues at all, and I can't see why I can't get back to those speeds.

Mark

School / University holidays put extra load on serving cells, Nothing wrong with 30Mbp/s

Any reason why you need 70Mbp/s? As loads change on serving cells so does the speed

Some people that live in the city can't even get 30Mbp/s

The install was done towards the end of March last year...it was lighting fast for a week, but since then has been less than half that speed.

If I got a consistent 30Mpbs, it wouldn't be too bad, but that's the peak. It affects the performance when trying to work from home.
Also frustrating that the technology can deliver twice that, but for some reason it's not.

That is almost 1 year ago new customers come on board and it's shared bandwidth

What do you need the 70Mbp/s for?

Yeah, but something happened after a week and the speed dropped in half. Wasn't a gradual decline over that time.

If you moved to a fixed lined connection what speed would you get?

And once again what do you need 70Mbp/s for?

If I moved back to a fixed line where we are, I'd probably get around 1Mbps. Not saying I need 70Mbps, I'm actually just trying to find out why my connection can't be as good as it was when it was first installed. I don't believe it's due to congestion/overloading as it doesn't matter what time I try and it also wasn't a gradual decline in performance, something happened after a week - it might have even coincided with a power cut.

Have you tried at 3am in the morning and then compared it to say 3pm?

Yeah, it still will max out around 30Mbps at 3am and later in the day towards 5pm, it might drop down to 10-15 Mbps.

When it was working well, it would be around 70 (the highest I clocked was around 120Mbps). Then in the afternoon/evening, it might drop down to 30-40Mbps.

Sounds like it's working as is should and actually don't have an issue so I don't get the reason for this thread sorry

sounds like you are fixated on speed and nothing else

You could check out the https://gis.geek.nz/celltowers site and see the serving cell and see if another is close by and point the antenna at another site

You are getting good speed so Vodafone will not see it as a fault as such

Yeah, but it's not actually working as it should - it was, for a week when first installed. RBI can clearly deliver much more than 30Mbps.
The fastest the connection the less wait time when transferring files and the more productive the connection is.

30Mpbs is a vast improvement on what we originally had using ADSL, but having seen what RBI can deliver via our equipment, it is frustrating that it can't deliver to that capability.

like all wireless connections including mobile it's shared bandwidth with all other users around you, The connection is performing well above minimum requirements for RBI

FYI the word Vodafone have used is incorrect ' Powerful ' I suspect they should be using the word ' capacity '

kinda sounds like a new tower has gone up that your now latching onto.

equally possibly for whatever reason, you are nolonger managing carrier aggregation on.

@Linux is right. Since RBI is shared bandwidth you basically get what you get. There is no guarantees.

This is working as intended and also at a good speed. Have you also checked if you can get other services either through a wireless provider locally, or even ADSL/VDSL? Posting where you are (you don't need to be exact) will help.

im sorry but you are incorrect, it is working as it should.

look at the link provided and see if there is another tower near by in a different direction that you could align your external antenna's to. check your router has carrier aggregation turned on, check 4g is turned on, maybe preform a factory reset on the router too.

yes it can deliver more speed but its highly condition dependant, and those conditions, be it weather, trees, buildings in the way, or just a whole heap of people connecting to the tower can cause it to slow down.
