The second Sky Muster satellite, built for the National Broadband Network (NBN), will be launched this week from French Guiana in South America.

NBN says last week's "temporary outage" issue is resolved Rural, regional and remote Australians still unable to re-connect

However, it comes after a particularly difficult week for the network and even previously satisfied customers say they are frustrated and not getting the network NBN promised.

NBN said it experienced a "temporary outage" affecting its first Sky Muster satellite, sparking a large number of complaints.

Kristy Sparrow from the group Better Internet For Rural, Regional and Remote Australia said a large number of people are still unable to re-connect to the service.

"There's been numerous problems from no connection at all," she said.

"There's also been people that can't get enough speed to do anything and others who haven't been able to connect to internet websites like internet banking."

Ms Sparrow said on Wednesday last week she received an email from her internet provider saying NBN would be carrying out maintenance on its Sky Muster service.

She could not use the internet when she tried the next day and, days later, many are still unable to connect, despite promises of improved services from NBN.

"People are beyond frustrated," she said.

"[Sky Muster] was sold to them as a game changer, and yet, in reality, that's not what we're receiving."

Portion of data can only be used during sleeping hours

In a statement, a spokesperson for NBN said last week's issue has been resolved.

"Sky Muster services were affected by a temporary outage last week. This has now been resolved," the statement said.

"If residents continue to have problems with their Sky Muster connection, they should contact their internet service provider."

Ms Sparrow said while her internet service provider has been cheaper and faster than her previous service, the roll-out of Sky Muster has been riddled with problems.

A Facebook page established by the group has been inundated with reports of dodgy installations and drop-outs, as well as issues with latency — the time it takes for information to travel from computers to the satellite.

There are also complaints about constrictive limits on data usage.

"It certainly hasn't delivered fair use data limits. The fair use policy is very restrictive in peak data, limiting the biggest plans of peak data you can buy on Sky Muster is 70 gigabytes," Ms Sparrow said.

Tammie Irons, who runs a cattle station on Queensland's Darling Downs with her husband, said they miss out on using more than half of their allocated data, because it is only available when they are asleep.

"I think I've got a 35 gigabytes peak and then 45 gigabytes to use in the off-peak hours, which … I'd be very surprised if I ever get close to," Ms Irons said.

"Somehow we have to work out a way where we can download and set downloads for certain times of the night."

Other rural business women, like Meg Kummerow, who sells drones to farmers, said she chose not to have Sky Muster installed.

"I needed unlimited internet for our business to bring it forward where it needed to go and also because I didn't feel comfortable using it when other people needed it more than what we did."
