[solved]wireless network configuration during installation

Hi, everybody, I'm new to Arch Linux. I've been trying to install Arch Linux on one of my old laptops for the last two days, but always get stuck at the install step when I type "pacstrap /mnt base", it always gives me:

error: failed retrieving file 'core.db' from EVERY MIRROR
error: failed retrieving file 'extra.db' from EVERY MIRROR
error: failed retrieving file 'community.db' from EVERY MIRROR

I thought it must be my network connection problem, so I checked:

iw dev wlp3s0 link

It gives me:

Connected to XX:XX:XX:XX:XX:XX#MAC of my router# (on wlp3s0)
                   SSID: NOT WIFI #my wifi id#
                   freq: 2462
                   RX: 8487569 bytes (73462 packets)
                   TX:32645 bytes (544 packets)
                   signal: -33dBm
                   tx bitrate: 54MBit/s

                   bss flags:          CTS-protection short-preamble
                   dtim period:     1
                   beacon int:       100

It clearly indicates that my laptop is "connected" to my wifi, but my router says it isn't. I think the wireless network configuration must be somewhere wrong here.

Could anybody please guide me to solve this problem so that I can continue the installation? Thank you very much.

Re: [solved]wireless network configuration during installation

"ip route"? (dhcp?)
"ping 8.8.8.8"? (ie. dns/resolv.conf issue)

Re: [solved]wireless network configuration during installation

I think the wireless network configuration must be somewhere wrong here.

So tell us what you did to configure the wireless network.  Ethernet is enabled (e.g. automatic) on the installation iso, but wireless is not.  What steps did you take to (attempt to) connect to your wireless network?

ping 8.8.8.8

gives me

connect: Network is unreachable

1.

ip link set wlp3s0 up

2.

wpa_supplicant -D nl80211,wext -i interface -c <(wpa_passphrase "NOT WIFI" ".........") -B

I just tried the third step:

dhcpcd wlp3s0

The thide step works!!! Now my installation is going on.   Thank you very much.@seth @Trilby
