Need help fixing tp-link mr3020

Hi guys,

So over a year ago I had a PB working with OpenWRT and TP-Link MR3020. Then I did something to mess it up... Don't know what anymore. I'm trying to fix it now, but I'm a n00b, so it's hard.

Problem:
- can't connect to the wifi
- redirect to page doesn't work

I think it's something with the DHCP... but how to fix it? I forgot my telnet password (yes, stupid me), but I can ssh root into it. Some info:



root@XZIeTItv:~# vi /etc/config/network

config interface 'loopback'
option ifname 'lo'
option proto 'static'
option ipaddr '127.0.0.1'
option netmask '255.0.0.0'

config interface 'lan'
option ifname 'eth0'
option type 'bridge'
option proto 'static'
option netmask '255.255.255.0'
option gateway '192.168.1.1'
option dns '192.168.1.1'
list dns '192.168.1.1'
list dns '8.8.8.8'
option ipaddr '192.168.1.111'


root@XZIeTItv:/etc/config# vi wireless

config wifi-device 'radio0'
option type 'mac80211'
option channel '11'
option macaddr '10:fe:ed:4c:bd:86'
option hwmode '11ng'
option htmode 'HT20'
list ht_capab 'SHORT-GI-20'
list ht_capab 'SHORT-GI-40'
list ht_capab 'RX-STBC1'
list ht_capab 'DSSS_CCK-40'
option disabled '0'

config wifi-iface
option device 'radio0'
option network 'lan'
option mode 'ap'
option encryption 'none'
option ssid 'PirateBox'



Does anybody know what's wrong and how to fix this?

Hi,
try to reflash it using failsafe mode [piratebox.cc]

Thanks for answering so quickly.
So I plugged it in again today and now it suddenly let's me telnet it again, but not ssh... When I try to set a new password he says he can't find passwd.

How do I get around a read-only file system?
Also: root@(none):?



Trying 192.168.1.1...
Connected to 192.168.1.1.
Escape character is '^]'.

=== IMPORTANT ============================
Use 'passwd' to set your login password
this will disable telnet and enable SSH

Hi,
you have a typo here

mount /dmount /dev/sda1 /mnt

that is the problem why your mtd did not work out.
