I have a VMDG480 and I'm being forced to manually reboot the device veru frequently (turn off and on) as I often find my devices (laptop, phones, tablets , etc) all seem to disconnect from the Wi-Fi or remain "connected" but can't connect to the internet. To compound this, I often find the web interface (to manage the router) slow or unable to load in a browser.
Am I alone or do others have similar issues and I'm wondering whether the device is faulty and needs replacement?
Any suggestions on how to correct my issues (troubleshoot) or proceed with replacement?
It may be your hub breaking down or it may simply be an issue with power levels on your connection. Can you post your Upstream and Downstream data please. To do this enter 192.168.0.1 into your browser's URL which should take you to your hub's management pages. Do NOT sign in but simply click on Router Status where you will find the data pages.
Those stats are fine, Upstream & Downstream power levels and Signal to Noise Ratios are all within specification, so nothing obviously wrong revealed there.
Perhaps it is an intermittent fault within the hub and a replacement might sort things out.
The one thing we haven't covered is the possibility of Wi-Fi interference from a neighbour's setup, so you could try changing the Wi-Fi channel ... see the video tutorial at the top of this Networking & Wireless forum. If you do change channel stick to either 1, 6 or 11.
The VMDG480 is a total fail, particularly on wireless. It is short of memory, short of CPU power and useless except in modem mode.
One its major faults is the reason why you have to reboot regularly. Its buffers can get so clogged that it has insufficient memory to deal with the data backlog and latency just grows (the search keyword RAMPING will reveal a mega-thread on the topic).
The VM bods tale a week or so to get to the thread and it's likely they'll declare your hub faulty and arrange a new model to be sent out. If you prefer you can call it in and maybe get a result (or a verbal wrestling match with an offshore agent who has never used any SH model).
Thanks for the prompt reply. I've been through the loop of changing the Wi-Fi channels before (a friend helped me with this). Currently the router is manually set to channel 8. I have an app on my phone (Wi-Fi Analyser) which still shows channel 8 sitting nicely in a gap between strong signals from my neighbour(s) which looks to be grouped on channels 5 and 11 (and lots much lower down the scale too).
Does this suggest the intermittent fault you suspect is now the most likely cause? If so what's the next step?
The chart is useful, yes channel 8 isn't ideal, *but* it's the only gap I see in my immediate vicinity (high density terrace housing). Not want to waste countless hours on the phone to VM, is the next step simply sit back and hope someone from VM event reads this post and takes action - is this likely, just lengthy as your earlier post suggests?
The answer to high density wireless conflict is usually to have the 5GHz channels available. There are way more 5GHz channels that don't overlap. If your devices are 5GHz compatible, you can either set the wretched VMDG480 to 5GHz and choose an uncontested channel, or you can await a Hub 3 which is dual channel.
