This Worked for me...
I had same problem. Called tech support & they gave me a fix , which worked super well, but after 12 hours my modem light turned red. Called Tech support again & took modem into store to either get a new SIM or replace modem. Got new SIM, got home and modem was slow again (0.08mps download). Reconfigured modem as per tech supports advice, got great speeds & then Modem light went red again. Called tech support again, they will call me with a fix tomorrow...... Not content I did some searching and decided it was one of the setting I used to increase the speed.
Found this guide & downloaded it. https://devicehelp.optus.com.au/huawei/b525-windows-10/connectivity/set-up-your-router-for-internet/
Great speed, modem working & tonight I am my son’s hero!
My initial mistake was thinking my modem had been correctly configured when I bought it and whilst it may have been, Network upgrades slowed speeds.
I have just read through all the Posts on this Subject, as I have been trying to find out what the maximum speeds are for the Optus WIreless Home Broadband. As Optus does not publicise it and after speaking via Live Chat with Tech Support which was useless and a waist of time, just told me a maximum of 2Mbps, but if getting 5Mbps that is good.
I came across from Vividwireless and remain on the same Plan that I was on with Vividwireless which has the max speeds of 12/1, which was the norm for All ISP's with wireless home broadband. I'm still undecided to change over to the Optus Wireless Modem and Broadband Plans, after reading the comments made here, or should I wait for the 5G Wireless Home broadband, as I am in inner Sydney.
My initial question which I posted on Yes Crowd, was about a Firmware Upgrade on my Vividwireless modem last week. What I was trying to find out, was the firmware upgrade on All modems or just Vividwirless modems? After the upgrade, for the next 2 days my speeds dropped from 12mbps to 4-5Mbps - was there a glitch? My speeds returned to 12Mbps over the weekend. No one on Yes Crowd or Tech Support could answer those questions.
What speeds do users normally average with the Optus Wireless Home Broadband?
Thanks Paddylee for explaining what the network is now to what it was.
As there are no Max/Min speeds, what is classified as slow speed?
Also, you mention Netgear 800s is a Cat11 device, but the Plan shows Huawei B525 modem - Cat6.
I'm confused with what you have mentioned to what is available.
I appreciate the information.
Paddylee, thanks for the information and your comments, much appreciated.
Tech Support provided me with this information, which I found not very useful, as he was talking about my Vividwireless mdoem. I am constantly getting the max allowed speeds 12/1Mbps, except for thise 2 dyas last week..
Gladwyn (12:23:31 AEST) : As per this modem you will get maximum speed above 2 mbps and as I checked your area the network is very good so the speed will increase eventually.
Gladwyn (12:34:50 AEST) : Any speed what you get more then 5 Mbps its consider as good speed.
At least I now have a better understanding of Optus Wireless Broadband, and the speeds that can be obtained.
