M100 - very poor speed

Hi folks,

I'm on M100 and my speed tests show around 32 Mbits and 10 Mbits respectively.

I attach the text from my Router status here and would be grateful if somebody could give me some advice please.

Thanks

Seamus

Re: M100 - very poor speed

I take it you are connecting over Wi-Fi ?

What is your connection like with a direct connection using a Cat 5E/6 cable between the Hub and a 1Gbs capable Pc/Mac/Chromebook and no other devices connected ?

Re: M100 - very poor speed

Hi Mike,

Indeed I was connected via WiFi.

101.4 and 9.67

Cheers

Re: M100 - very poor speed

IP provided Hubs are renowned for their poor Wi-Fi, and at the best of times Wi-Fi is a fickle beast that can be affected by numerous things such as distance from the Hub,  building construction, other electronic devices, neighbouring Wi-Fi, basically all sorts.

VM supply to the Hub, after the Hub it is up to you.

Many on here, myself included advocate the use of a third party Gigabit capable Wi-Fi router or Mesh system.

Re: M100 - very poor speed

You may be as well refining your Wi-Fi management, it will certainly help keeping track of your Wi-Fi frequencies.

Best done with a cable connected device.

Instructions for Hub 3

Log in to the Hub.

Advanced Settings > Wireless Signal > click ‘Disable Channel Optimization’ > Click ‘Apply Changes’.

Advanced Settings > Wireless > Security > Add 2 to the 2.4GHz Channel name > Add 5 to the 5 GHz Channel name > Click ‘Apply Changes’

You can leave the passwords the same as they are. 

Log out of the Hub.

You will need to reconnect all you Wi-Fi devices some will want to connect to 5Ghz and some to 2.4GHz and some will connect to either.

2.4GHz is a stronger signal but slower than 5GHz so if you have problems on 5GHz change to 2.4GHz.

Re: M100 - very poor speed

Hi sosullivan

 

Thanks for posting.

 

My apologies for the lower than expected speeds. 

 

I've ran a check on the system and no issues are showing. There is however one device showing as too close to the router. Could this be connected via Ethernet, or moved away from the router, as this is potentially limiting the bandwidth.

 

Kind regards,

Re: M100 - very poor speed

Thanks John,

Are you able to tell what that one device is? I only have TIVO box and a raspberry pi both ethernet connected.

Thanks

Re: M100 - very poor speed

Hi Seamus,

 

Is there anything else close to the router that's connected wireless, like any streaming devices etc?

Re: M100 - very poor speed

Hi there,

Yes I have a Chromecast plugged in to HDMI and connected wirelessly.

Hopefully that's not going to be the cause of slow speed?

Re: M100 - very poor speed

Hi John,

So I'm using a raspberry pi set up with pihole to stop ads. I've switched off DHCP in the Superhub and switched it on in the pi. 

Nothing else out of the ordinary 

Thanks

Seamus
