We live in a village where power cuts are a weekly occurrence, ranging from a second or two to hours.

Every time, I have to do an internet reset which involves five minutes wait + a restart. (I have to reset the wifi router also)

The mystery is that my wife's 8 year old PC, connected to the same router by cable, never suffers this problem. So apart from the obvious solution of buying a UPS, the point is that my wife's PC has something that mine doesn't. (or vice versa... ?) I have written to two computer forums without getting an adequate response, maybe someone here has experienced similar problems?

Thanks.

Its a strange question...do you mean the pc does not loose time and date during power cuts ? Its normal that a PC has a small battery that keeps the internal clock running along with other user setting in the BIOS.

 

Modems,routers etc normally dont have a backup battery,they store their settings in a non volatile ram chip NVram ...time and date is obtained from the internet

The modem and router will work perfectly well with the wrong date and time set. There should be no need to enter settings on the modem or router after every power cut....although it is possible that a

"brown out" (low voltage) could corrupt data in the NVram chip

then you may have to "reset" and re enter your user data.

 

 

 

I'm not sure if you have explained the problem correctly, but change your computer battery.

Are they both using the same operating system?

 

I know with my Win 7 desktop if the Internet goes off, I usually need to disconnect and reconnect to the wifi router to get an Internet connection, whereas my Linux box just reconnects without a fuss.

Thanks. There's nothing wrong with my explanation.

Not sure if I understand you but the PC clock in the bottom corner maintains correct time and date. Dell has a pretty good in depth analysis tool and it has never indicated the slightest problem.

 

Are you connected by cable to your router, the same as your wife?

yes.....

Don't know but may be your internet card driver problem. Maybe try updating your driver or look in that area.

I have Dell XPS 13 and the laptop was the best one. I use Samsung Galaxy S8 as wifi connection if there is a power cut.

So are you are saying ...you have one computer that has no problems reaching the internet after a power cut...but another computer requires the modem/router to be "reset" before gaining internet connectivity ?

Is the "bad" computer set to a "static" ip address or does it automatically get an address from the router via DHCP ?

How do I find that out?

'How do I find that out?'

Probably easier explanation if you Google it. Keyboard in something like ' In windows xx how to set static IP address'. This should lead you to the area to check if you get your address from DHCP or if you have a static IP address.

Did you check or update you network drivers?

When you fix your computer, you're still going to have the router problem after a power fail, so you probably need a UPS for the router.

1. Please confirm, when the power cuts, the router, your pc and your wife's pc are switched off?
2. do an internet reset - do you mean your PC? If so what do you mean by  "internet reset"?
3. (I have to reset the wifi router also) - Do you mean just a restart off/on the router or a factory reset?

 

I have written to two computer forums without getting an adequate response,

 

Hard to tell what the problem even is. Maybe if you wrote an adequate description? Why even mention your wife's computer is connected by cable if yours is also?

Didn't you read post #5, his description is adequate for us to diagnose the problem

Yes I think you're correct.

Seems like a DHCP problem to me.

Open control panel, internet, choose ethernet

On the ethernet card choose settings

go to Internet protocol ipV4 and again choose settings

 

If one has a static ip and the other one obtains it from the modem, the problem is solved.

 

You might want give both computers a static ip address on the upper end of the ip range, like 192.168.1.98 and 192.168.1.99 or similar.

 

Don't do that with your mobile phone!

I run 4 computers they all start automatically after a power cut.

You sure its not the battery in the bios?

Yes, agree, it sounds like an IP-address problem, when restart of the wifi-router is needed, i.e. reset the DHCP.

And yes, static IP-address might be a solution.

 

Should also be able to be done in the wifi-router's DHCP settings by binding an IP-number to the chosen PC's MAC-address, depending of router-model it could be under "Network" > "LAN" > "DHCP binding", add an IP-address (see above) and the PC's MAC-address; the MAC-address could be found in "LAN" > "DHCP server" in the "Allocated Address" table, where a PC-name is shown together with the PC's MAC-address and allocated IP-number. Don't reset the router to factory settings when restarting, as you'll loose DHCP bindings.

 

However it's always advisable to protect your PC with an UPS, which both provides a stable voltage, and eliminates the short power cuts of few seconds and up to a few minuts, and furthermore gives you enough time to store files and close down correctly in case on longer power cuts. Investment in an UPS, or two, can be well spend money.

I live in a rural village and we lose power all the time.  Buy a UPS that doesn't have an audible alarm (or one that you can turn off.  We also have emergency lighting which is essentially a battery with a couple of LED lights on it which uses very little power.  Power goes off you have lights and Internet.  Your set! 

i have notebook and no proplem if elektric cut, keep pc open all cuttinf time, but table pc has proplem and many cnc machine,3D prointer fail many work cut ewery ewening manytime short time. i buy UPS help lot pc and 3D printer can keep work procress not end and fail all work now. but pc need more power UPS, need buy many UPS more then no have proplem newer ir elektric cut shirt time. we village have proplem cut shirttime about 1-5 minity only, sometime if rain lot cut some hour and thats no UPS help, or need build battery room and big inverter system reserve. whit solarpanels. if start build.

I got a good ups i can go on for half an hour or so if the power goes off.. But no fan no aircon.. so its not really comfortable if you lose power. 

Everything I have resets itself when the power returns, similar to a reboot.

not sure why yours would be different unless it is truly ancient.

This only happens when my PC is switched on.

Internet reset - control panel, Network and Internet options, reset.

I pull the router plug out for a minute.

Sorry I took so long to answer

Could you please try reversing the roles of the two PC's?

Your PC connected via cable and your wife's PC over WiFi?

(or have you tried this already?)

Did you try all the options already suggested yet?
