Hi @yok0ross, thanks for getting in touch and I'm sorry to hear you're having speed issues as of recent. Checking your connection from this side I can see we're currently getting 36.7Mbps download and 8.0 Mbps upload to the rotuer with no signs of errors or underlying issues showing.
Can I ask then, the speeds you've observed recently, was this over a wired connection or wireless?
If wired, then please could you re-test the speeds making sure there's no other applications or devices using the connection at the time as this can heavily skew results.
If on a wireless device then it hints that wireless interference could be impacting the wireless performance you're seeing and in which case I'd advise going through the steps below on how best to optimise the wireless to best suit your property and surrounding area moving forwards which should help.
The guide below will show you how to log into the router and change the wireless channel as it's usually another router in the area on the same or similar channel that will be causing issues for both wireless frequencies. Before picking a channel I'd suggest downloading a free app called wifi analyzer which will scan your area for all the routers and show what channels they are on between 1-13. Although the above app isn't essential it helps you pick where your router would be best in terms of channels and saves a lot of time doing it via trial and error.
1) To connect to your Hub One, you will need to open a browser and go to 192.168.1.254 If you have any issues doing this via Wireless, we recommend trying to do it via Ethernet cable instead.
2) You should come to a page with information about your connection, click 'Advanced Settings' at the top and it will ask you to sign in with a Password. This is located on the back of your router under 'Admin Password'
3) Select the option for 'Wireless' followed by '5 GHz Wireless'. What we want to do to begin with is turn 'Sync with 2.4 GHz Wireless' to 'Off' and update the SSID to be different. The easiest way would be to add '-5G' to the end so it is identified as its own connection. Once this is changed, we will need to keep an eye on it for a day or 2 to see if the issue continues. If it does, the next step would be to change the wireless channel. Keeping in mind the original 2.4Ghz unchanged name network connection would be the best to connect your devices to for a stronger signal.
(When deciding which device goes on what frequency keep in mind that the 5GHz is designed for close range stationary devices and standard 2.4GHz the one which gets the wireless around your property further.)
4) Following the above guide to get to your 'Advanced Settings' page, you will need to change the settings within the 2.4 GHz Wireless tab and the 5 GHz Wireless tab.
5) Under the correct heading, you will need to find 'Channel Selection' on the list and change this from 'Automatic' to any one of the other channels, This can also need doing under '5 GHz Wireless' to cover both signals. Give it 3-4 hours of testing to see if the issue still persists and try to change the channel again if you see little or no improvement.
Let us know how it goes.
