I fail to log in the wifi - TP-LINK Computers & Internet

at home,work or at the airport (wifi)?
wgn1, wild guess #1 , HOME ! (answering to home.
well do all things wifi fail at home or just the G1. fails?

if yes all fail, that is a wifi router problem. or forgot your log in credentials?
No only G1 fails!
did the G1 ever work for you at home everbefore??? hummmmmm
buy used, and wifi dead? (history not told)
did you know most old PCs have no wifi new this is a fact.
it must be added, called a CARD (WIFI)
2014 made, 8 years old
I see goons sell them used as new on amazoned.
still used it is.
sold new with on of these 4 HP allowed cards
HP also bans, other cards (black listed by HP. (not good that)

• Realtek 802.11 b/g/n (1x1)
• Meditek 802.11 b/g/n (1x1) with Bluetooth v4.0 combo
• Intel Dual Band Wireless-AC 3160 802.11 a/b/g/n/ac (1 x 1 ) WiFi with Bluetooth 4.0 combo
• Intel Dual Band Wireless-N 7260AN 802.11 a/b/g/n (2 x 2) WiFi with Bluetooth 4.0 combo

test #1, go to device manager and see what wifi card is there.
or missing, totally..
the driver must be there and from HP.com or it will not work.
If w10 plug and play fails. using wired ETHERNET cable to the router
this PC never oncc came with w10 , only w7 or W8
so how did W10 get here.?
but lucky you , HP does have w10 64bit wifi drivers here, in fact, all drivers of this PC..

so next you ask how to get them if WIFI is dead now.
well 2 ways.
use the ethernet port to a cable same name to the router port same name.
or get the drivers, using a working internet PC and copy them to a thumb drive then move the thumb drive to dead wifi PC
and load them, ( 1 driver it is and matches 1 of 4 cards)

here is the hit list
1: the card must be there.
2: and be a HP card. (others do fail)
3: and a matching driver loaded.. card/driver/OS matched and HP matched..
4: and connect,. works. now. using proper credentials wifi

that is how the cookie crumbles..

wifi or ethernet,?
we can't guess what you have for your connection class.
but if wifi, you need to reset the wifi in the TV
and then use your credentials to log in the TV to routers wifi.
if that fails reset the Router (or AP wifi Access Point device)

Its a Password protected WiFi Network.

defective wifi unit in the phone. time to get a new phone as they don't fix those.

(similar type problem in my samsung, galaxy, S4. the tech at the booth asked me how i kept it running this long.... had it 6-7 years now....)

FYI: cellphones are designed for obsolescence - within 3-4 years, the battery will fail - if nothing else does - and the batteries are no longer replaceable by a user.

JUST SIMPLY RESTART YOUR COMPUTER THEN CHECK YOUR INTERNET AND WIFI SETTINGS ,RECONNECT TO YOUR WIFI THEN RESTART YOUR INTERNET OPEN SITED YOU FAILED TO LOG ON TO AND CLICK REFRESH THEN SIMPLY JUST SIGNIN AGAIN

First unplug the power then plug back in it will restart. you should see the front lights flash as it resets if that fails read on... The blue to light will rotated blue led if wifi is working. double check your lan cord coming from your dsl,cable or sat box.
on the back there is a small hole use a pin to hard reset it. you have to hold the pin in for around 10 seconds. This will reset it factory default. You may have to log into it to enable wifi. usually after the reset. type 192.168.1.1 or http://www.routerlogin.net or http://www.routerlogin.com into your browser
a login screen should appear.
Username: admin
password: password or 1234
these are the normal default but may have been changed by someone setting up your router.
Router do fail often they just die out of the blue. this is an older wifi router failure may have occurred. if no lights flash or regain a solid status then it may have died.. good luck

Things will depend on how the power went out or why. If it was a thunder storm you may have had a power surge as it went out.

You should try using a cable plugged into the port. The log on and check to see if the wifi is off. If the unit reset it self to factory the wifi is disabled. Hopefully that is all it is. If the uni is older the wifi section may have failed. Netgear is good stuff even the home grade units so they don;t die often unlike other brands with Link in the name ;-]

Unfortunately if you can't just turn the wifi back o it is time to replace it.

1. you will have to log into the router and add your wifi device to the wifi allowance list so that the router will authorize said device.

log onto the acer website,support & downloads then look for wifi manager or wifi link and download from there
