LIghtning zapped our routers


[link to this post]
 
Along our country lane, both I and a neighbour had our routers zapped on Friday night by lightning close by.

Any tips on surge protection that won't affect broadband speed?

Thanks

I still unplug my phone line when lightening is nearby
(2 seconds from flash to rumble means it is less than half a mile away which is close enough to me).
In principle I would also unplug the tv aerial if roof mounted.

The recent storm was in the middle of the night so I was't bothered about internet but did stay awake for a bit to watch the show.

It's one way to be sure however I cannot deny it "affects" my broadband speed.

This mains lead is one of the very best and should be used all round the house wherever possible. it is the only one with RF Conditioner-Frequency-Interference built in at this price point

Can you enlarge on the present state of your routers, please?

If they have failed on the Mains (Adaptor) side, then a Surge Protector MAY or may NOT have protected them.

Depending upon the form of the damage, if the Mains (Adaptor) side is still working (LEDs coming on), there is a slight chance that a Factory Reset just might get them operational again.


If the failure is on the Phone/DSL side, then it is unlikely that anything would have protected them, apart from total disconnection from the Phone circuit.

========================

Both of which raises the question, how did you get back on-line?

Did a Factory Reset work?

Did you replace the Router?

Did you replace a Mains Adaptor?

Etc.

If lightning is around, DON'T wait until the storm is on top of you as you might get a strike out of the blue (sorry, pun not intended) as you are unplugging things.

I doubt a surge-arresting socket will help unless the storm causes a power surge by striking overhead supply lines. But, as they are so inexpensive, it's a good precaution.

It's more likely to get hit if you have a drop-wire connection rather than an underground telephone wire.

The chances of a direct strike are remote, but there will be considerable radio frequency high-energy pulses which are more likely to cause problems.

If there is a direct hit, the Router will be the least of your problems. Also, don't use the telephone if its directly connected to the line as you could get zapped too. DECT phones are ok as they connect wirelessly.

The router is likely powered by a switch mode transformer, any old cheap as chips surge protector will work on that and offer protection from general strikes nearby and other surges, although any surge the power supply cannot cope with and you'll need more than a surge protector. A direct strike to the mains supply or the house for example, and no surge protector (not even that one) will help. In that case you would need all electrical devices unplugged, which is why the general advice during a lightning storm that is nearby is to unplug electrical goods (All electrical goods).

That also won't help in the case of a strike on the telephone cable into the house. The master socket includes surge protection for voltage across the pair coming in from outside, however in a strike on the line the surge comes down both wires and will find it's own way to earth (typically through any mains connected devices attached to the phone line, but it's not unheard of for it to earth through a person on the phone).

I used to have a surge protector on my ADSL line, it worked well, was reasonably cheap, from maplin, but it does not claim to be rated for VDSL (BT FTTC broadband, and the like) and doesn't fit on the shiny new faceplate for FTTC. It is also worth noting that I did not have a marginal line, and it did effect the SNR a little (but not enough to cause problems).

it states 6000 which is higher but i wouldn't read to much into the figures as there is no way you would be able to tell. The RF part is much easier to say that it works i find as everything in the house just seams much quieter be it from the tv no picture glitching no hum from the hi fi etc

i would give it a try and if not to your liking you can return it

this is the newer version from belkin although i prefer the Tacima

Keep in mind that such devices only protect against the typical spikes etc of interference; but are akin to sea walls relative to real on-shore gales coinciding with high tides; and that actual lightning strikes on lines, whether phone, mains etc are similar to tsunamis.

Induced voltages during electrical storms (as opposed to direct strikes) can be well beyond the capabilities of surge protectors.

The only real lightning protection these devices can offer is the insurance, which has a good number of clauses to it.

A lightning bolt will NOT be stopped by any of these, induced currents from near strikes and mains noise , but a strike on your mains or telephone wiring will simply be looking for a route to ground and a few mm gap or less from a surge protector blowing will be of little worth.
