any suggestions to improve signal?

despite the online check, and the check in the store before I bought the modem today I'm getting 1, sometimes 2 bars of 4G coverage.

I've tried all sorts of places in the house (different rooms, both floors) and doesn't seem to get any better.

My (Telstra) phone has no problem getting a signal and significantly better throughput (but their data costs an arm and a leg, hence trying Vivid...)

Are the antenna connections on the back for 4G or just WiFi (and if they do/can help 4G any recommendation on what to buy... or can I just steal the old ones off a wifi router as they appear to be the same connector?!)

What Suburb/Postcode are you in?

Vividwireless does have a 14 day Moneyback Guarantee Policy.

Postcode is 3131 (Nunawading)

Performance isn't terrible - despite showing 1 bar earlier today was getting 8-9Gbps and a <20ms ping, thought this evening it's down to ~2Gbps/50ms.

Hoping to avoid the money back path as our ADSL is pretty horrible as well, so if we can get better signal this is a better solution ;)

I would say there is a couple of issues contributing to the slower speesd:

Showing on the Optus Network Status map, there is one tower over in Box Hill and two towers in Mount Waverly that have a problem, and customers who connect to those towers are pushed onto the next best tower(s) which the modem decides. As well as, many other towers surrounding your area that is currently having work done on them, again, pushing customers over to other towers. This creates a cascade effect. Optus maintains the towers whether it be a problem with Optus or Vividwireless.

All this as well as peak times creates congestion on the tower which causes slower speeds. With the World Cup football and the online video channels, Netflix, Stan all contributes to slower speeds.

You can check on the map by clicking on the following link. Click on the Outage Tab and insert your Postcode/Suburb. You can click on a tower icon and more information will display. Red tower - problem. Orange tower - work being or to be done.

If needed, you can contact Tech Support and have them look at your connection. They may ask to move the modem.

thanks! looking at the map around us, the closest 6-8 towers are all showing green, and now we're back up to 9-10Gbps according to

will walk around the house and try some other places later and see if I can get more than one bar showing... and might check with support tomorrow...

thanks for your pointers to help a newbie :)

Showing Green just means there is no problems or work being done. It would still show Green if it was congested.

We normally advise to use to check speeds.

I just did speed tests at the same time and you can see the difference in speeds: = 3.8Mbps = 6.46Mbps

Personally I prefer speedtest.NET (not .COM) … but the main thing is to use a consistent test each time.

I know the Nunawading area pretty well, as I drive through it down Maroondah Highway every day on the way to work in Box Hill, but I am away on holidays at the moment and cannot do much about testing.

You might get some incremental improvement and better stability if you can find steady 3-bars or 2-bars of signal, but the jump will probably not be huge. When you do the "moving the modem around" thing, also keep in mind that it works in 3 dimensions, so also try just raising or lowering it a little (e.g. but a book or two underneath it temporarily) and try rotating the modem 10 degrees or so at a time; these small changes can sometimes help get the modem into a sweet spot for signal.

If you login to the web interface of the modem, you will see the stats from the signal and can use these as a better and more accurate guide to signal strength and quality (and I should mention that signal Quality is a more important measure than Strength).

thanks! you're not missing much right now... weather is miserable here ;)

will play with moving it around some more... already tried the small rotation and height increments (had the same dance with the TV antenna as well until the landlord put one on the roof for us!)

that said, Vivid is way better than our Belong DSL at the moment which has been down since the 18th, and the ETA for an 'update' is the 25th!

finally found a good location in the house - solid 3 bars on the front of the unit, though the stats indicate it could still be better:

RSRP: -108dBm (Moderate)
RSRQ: -7dB (Excellent)
RSSI: -79dBm
SINR: 0dB (Moderate) [sometimes shows -1dB (Poor)]

amusingly that put it in a part of the house where the wifi hop to my machine is now reduced, so having to run an ethernet cable to improve that!


ozzcaddy-MODERATOR wrote 48 weeks ago

Great to hear you have found a good location.

Have you thought about an access point/WIFI extender router to provide wider Wi-Fi coverage.


OBM wrote 47 weeks ago

good idea on the wifi extender... I've just re-purposed the Ethernet-over-Power setup that we'd been using with the Belong DSL (reason we'd bought the Vivid modem was DSL has been down now since the 14th and no ETA on a fix!).

I know some folks aren't fans of network over power but we seem to be pretty lucky with it in our place... new construction and the wiring seems clean and noise free

I use the Netgear Night Hawk AC1900 Access Point router, that has twin bands 2.4 & 5.0 GHz.
