i have a router in the living room at home. i extended a long network wire to my bedroom and i connected that wire to a second router in my bedroom a couple of hours ago the internet in the living room and my bedroom spoilt. the exclamation mark in a triangle appeared next to the wifi icon and it said can't connect to internet. it was like that in all the laptops in my house. i switched off the router in the living room and i switched it back on. that fixed the internet in the living room but the internet in my bedroom stayed spoilt. i couldn't get the internet in my bedroom to work. i switched my router off and on many times and the internet in my bedroom would not come back i connected the laptop to the long network wire which comes into my bedroom. the internet worked. i connected the long internet wire to the router in my bedroom and then i connected another network wire from that router to the laptop. there was no internet and the exclamation mark in a triangle appeared next to the wifi icon. i gave up and i called a technician to come to my house first the technician connected the long network wire which comes into my bedroom to the laptop and then he went to cmd and he typed a bunch of ipconfig commands. after that he connected the long network wire to the router in my bedroom and he connected network wire from router to the laptop and he typed more commands in the cmd and then the internet was fixed in my bedroom can anyone please tell me exactly how did the technician fix the internet in my bedroom and what were the commands that he typed in the cmd when the long internet wire was connected to the laptop and when the network wire from the router was connected to the laptop?
He fixed it by ipconfig commands alone? No call of router's web page (settings) and adjusted settings there additionally? BTW: Why didn't you ask the technician himself about the commands?!?
i asked him how he fixed it. he said there was a wrong configuration he visited the router config page but he didnt do anything there. he fixed the issue in cmd. i guess that my router was generating wrong ip address range and he fixed that. do you know what he did?
I would have expected he set the second router as bridged or AP, so there is just one network ssid for all connections and one DHCP server.
Could think he used /renew (and /renew6) to force fetching a valid IP from the DHCP server. And maybe /registerdns to reinitialize all DNS records.
he didn't do anything. he just typed in cmd and the issue was fixed. when i asked him is it fixed he said let me check and then he opened the router config page but he didnt do anything there and he just clicked on some menu tabs and that's it. i need to know what he typed in cmd
so he did ipconfig /renew and those commands when the laptop was connected to the long network wire and that fixed the issue? do you mean that the router in the living room gave my router a wrong ip address and the /renew undid that? did he have to do /renew when the network wire was connected from my router to the laptop?
Checking the config: ipconfig /all Fetching a new IPv4 from the DHCP server: ipconfig /renew Fetching a new IPv6 (if used) from the DHCP: ipconfig /renew6 Re-registering DNS resource records for adapters: ipconfig /registerdns Flush the DNS cache: ipconfig /flushdns
he typed those commands when the long networking wire was connected to the laptop and that fixed the issue? did he type any of those commands after he connected the long networking wire to my router and then network wire from router to laptop?
My guess is the tec either bridged the WAN to the Lan on the second router and turned off DHCP or just hooked it up to to the Lan side and turned off DHCP, You just did not notice because he is fast since he does this everyday. Your routers were probably both doing DHCP on the same subnet and they don't like that at all. As for the ifconfig commands he probably used either a couple or all of these, I strung them together it's a bit quicker doing it this way. Open a cmd prompt as admin and paste this: Code: ipconfig /release; ipconfig /renew; ipconfig /release6; /renew6; ipconfig /flushdns; ipconfig /registerdns
those commands need to be done for the router in the living room only and that was when the long networking wire from the living room router was connected to the laptop?
UAH, that's normal, called "Router Magic". You know the 2 cents trick behind your ear? Same Magic man! .... Wizards everywhere ......
ipconfig depreciated ..... lemme grab now it's getting hot ... so let it pop... Spoiler: Router Magic explained Edit: On a serious note, I'm pretty sure what you saw wasn't even ipconfig, I'm sure he used a telnet session to simply reboot the router.
He said "ipconfig ONLY. Don't you listen? Personally, I'm rather using the netsh.exe commands for diagnosing network issues. Example for displaying all associated IPs netsh int ipv4 show ipaddr netsh int ipv6 show addr
Surely he logged into the second router either by HTTP or Telnet and set it to bridged mode and attached it to the source AP. I've never encountered a consumer grade router with stock firmware smart enough to set itself up as a network extender.
