Hi all, I'll try to be as descriptive as possible here, please bear with.

I have 3 x Deco M5 AC1300 units.

• VM hub is set to modem mode
• Unit 1 downstairs is hard wired to my Virgin Media hub - No issues with speed (200MB +)
• Unit 2 upstairs - No issues with speed (200mb+)
• Unit 3 upstairs has a PC connected to it with ethernet cable - Issue with speed on both the PC and wireless (7 to 12MB)

What I've done so far.

• Ensured all Deco units are up to date
• Rebooted all Deco units
• Unplugged PC from Unit 3 (The one with speed issue), rebooted and left PC unplugged and connected a wireless device (to ensure PC wasn't causing the problem) - Slow speed
• Brought said wireless device downstairs so it connected to Unit 1 - No issues with speed
• Took wireless device back upstairs so it connected to unit 3 - Slow speed
• Tried different WIRED device (laptop) and connected to unit 3 - Slow speed

To summarise, it appears that I have an issue with just one of my Deco units, giving slow speeds on both wired and wireless devices.

Please could anyone offer any advice?  More info maybe required, please ask
