i have never once in all the years ive been dealing in IT which is 14 years found a router that suddenly corrupts settings just because its powered off and back on again.

They are designed to hold their settings thats the whole point of them.

The wondrous Superhub is quite capable of resetting to defaults all by itself even without being power cycled. Check the VM community board for scores of complaints about exactly that.

I switch my router off overnight (not a superhub though as I'm not with Virgin). People do sort of assume that switching on/off is more likely to make kit fail. I wonder if that assumption is correct for modern electronics. It may just be a memory throwback to when electronic devices had thermionic valves .

In my own experience switching them on and off a router increases chances of it's config getting corrupted (so it needs to be reconfigured), so by turning it off every night you might be increasing the chance of this happening by 100 times or so.

One of my friends turns his router off at night to save electricity and is on his 5th one in 3 years as they keep mysteriously failing, but then again he does buy belkin and netgear so that might also be something to do with it.

It's absolutely correct, hardware failures are by far more likely at power on time.

Apologies for resurrecting this thread, but it relates to my own problem.

I am suffering regular problems using my Virgin Media Superhub where, although it indicates that I am "connected", I sometimes get the message "no internet connection". This occurs on both my own and my wife's laptops at the same time, so that would suggest a problem with the router or further down the line.

It can usually be resolved by turning off wireless (F8), then on again, but I feel this shouldn't be necessary.

When I speak to Virgin Media, the stock answer is to turn off the router, wait for two minutes and then turn it back on again. This is in direct contradiction to most comments on this thread, and I tend not to believe them (Virgin).

Does anyone else have this problem? What would you expect Virgin to do about it?

If you constantly have to turn it off and on, there is a fault somewhere. It may resolve it - but if you are persistently doing it, you're just masking a fault. Most people never turn their routers off.

Request a new hub or an engineer visit...

Thank you both. I suspected as much.
I'll record the problems as they occur over the next week or so, then get back to them and suggest they are talking a load of codswallop!

No advantage really it uses so little power over a year. You can however get full speed back unlike ADSL as Cable either syncs or it dosen't

I have the same problem and have finally given up on the SH and bought my own AC router. I'll be setting this up this weekend.

When this happens it is on wireless only (both 2.4 and 5 GHz bands) and wired continues to work ok.

I've had the wireless lockup when trying to transfer large files to my NAS.

In relation to the original thread about switching on / off this explanation might help.

Thinking about switch on, this is not instantaneous. The supply to the electronics will rise from 0 volts to the working voltage (typically 5 or 3.3 volts). This may take 10's of ms.

For a period of time the voltage is in an intermediate state and for logic circuits this is not a normal design condition. This can result in current and power stresses that do not occur in normal operation.

The best way to reset the SH is via the menu item on the web interface (if accessible!). Power remains on during this.

Whilst an indeterminate logic condition on power-on is a possibility (which would be reset on a further power-cycle), the main risk at power-on is stresses from a brief inrush of energy. In the Old Days, this would be into the mains transformer as its magnetic field built up, and also charging up the smoothing capacitors. These days with switched-mode power supplies, it will just be the capacitor(s) charging up. I believe. My electronic design experience is now nearly 40 years old....
