Intermitent connection to a TL-WR741ND v2.4

[monq]

I have a TL-WR741ND v2.4 router with Gargoyle 1.6.1 installed. It's acting as a wireless repeater; the configuration looks roughly like this:

Code: Select all

config wifi-device 'radio0'
        option type 'mac80211'
        option hwmode '11gn'
        option macaddr 'xxxx'
        option htmode 'HT40+'
        list ht_capab 'SHORT-GI-40'
        list ht_capab 'TX-STBC'
        list ht_capab 'RX-STBC1'
        list ht_capab 'DSSS_CCK-40'
        option channel '11'

config wifi-iface 'cfg2'
        option device 'radio0'
        option network 'lan'
        option mode 'sta'
        option client_bridge '1'
        option ssid 'xxxx'
        option encryption 'psk'
        option key 'xxxx'

config wifi-iface 'cfg3'
        option device 'radio0'
        option network 'lan'
        option mode 'ap'
        option ssid 'xxxx'
        option encryption 'psk2'
        option key 'xxxx'

My problem is that from time to time I lose all connectivity to it and the rest of the network, and this seems to aggravate when the connection between the router that is being repeated and the router with Gargoyle is not very strong. This is what happens, even when connected via ethernet:



The problem solves by itself if I remove the antenna from the Gargoyle router, which is weird -- the connection between both routers is not very strong, but it's not as weak as to justify this, and after all, I should be able to reach the Gargoyle router via ethernet whatever the conditions are.

I've tried to change to 11g, I've changed htmode to HT20, I've changed channels in both routers, and nothing helped.

Thanks in advance.
