mr_skater99 Posted September 1, 2012 Share Posted September 1, 2012 Hi all, First post - will try and put in as much data as i can - but if i miss anything let me know. Got my Mark IV a week or so ago and been messing around with it. Upgraded to 2.6.1. I'm now trying to get a stable 3G connection to Telstra (i'm in Australia) using my Sierra Aircard 880U The problem i have, is i can get the modem to work - and get internet - but am having a strange issue with keeping the connection up. Initially i could get the connection up - and it would last anywhere from 10 seconds to a few minutes. I'd then get a message similar to the log below - and it would disconnect. After a lot of googling and trying different settings both in the 3g.sh script as well as other parts of the ppp config i realised power might be the issue. So until i could get my hands on another adapter i turned off the internal wireless and low and behold i kept the connection up for over 30 mins. As soon as i turned the wifi back on - the connection died. So i found a 12V 4.5A adapter to replace the 12V 1A adapter i was using - but i have the same issue - with wifi on the 3g will not stay up. Is this a power thing - or is it something else altogether? I'm at a bit of a loss. I currently have the following as my 3g.sh script addition (have played with this quite a bit): *1199:6855*) echo "Telstra Sierra Wireless Modem detected. Attempting mode switch" uci delete network.wan2 uci set network.wan2=interface uci set network.wan2.ifname=ppp0 uci set network.wan2.proto=3g uci set network.wan2.service=umts uci set network.wan2.device=/dev/ttyUSB0 uci set network.wan2.apn=telstra.internet uci set network.wan2.defaultroute=1 uci set network.wan2.ppp_redial=persist uci set network.wan2.keepalive=1 uci set network.wan2.pppd_options=debug uci set network.wan2.pppd_options=noauth uci commit network usb_modeswitch -v 1199 -p 6855 -S 1 sleep 10; rmmod usbserial sleep 3; insmod usbserial vendor=0x1199 product=0x6855 sleep 5; /etc/init.d/firewall disable; /etc/init.d/firewall stop logger "3G: firewall stopped" iptables -t nat -A POSTROUTING -s 172.16.42.0/24 -o 3g-wan2 -j MASQUERADE iptables -A FORWARD -s 172.16.42.0/24 -o 3g-wan2 -j ACCEPT iptables -A FORWARD -d 172.16.42.0/24 -m state --state ESTABLISHED,RELATED -i 3g-wan2 -j ACCEPT ;; Here is a snippet of the logs from when i have a stable 3g connection and i turn on wireless: 00:08:43 Pineapple daemon.notice pppd: Connection terminated. 00:08:37 Pineapple daemon.notice pppd: restoring old default route to br-lan [172.16.42.42] 00:08:37 Pineapple daemon.notice pppd: Serial link appears to be disconnected. 00:08:37 Pineapple daemon.notice netifd: Interface 'wan2' has lost the connection 00:08:37 Pineapple daemon.info pppd: Sent 20076 bytes, received 20076 bytes. 00:08:37 Pineapple daemon.info pppd: No response to 1 echo-requests 00:08:37 Pineapple daemon.info pppd: Connect time 4.6 minutes. 00:08:37 Pineapple daemon.info dnsmasq: using nameserver 184.108.40.206#53 00:08:37 Pineapple daemon.info dnsmasq: using nameserver 10.4.81.103#53 00:08:37 Pineapple daemon.info dnsmasq: using nameserver 10.4.182.20#53 00:08:37 Pineapple daemon.info dnsmasq: using local addresses only for domain lan 00:08:37 Pineapple daemon.info dnsmasq: reading /tmp/resolv.conf.auto 00:08:31 Pineapple kern.info kernel: [ 511.440000] br-lan: port 2(wlan0) entered forwarding state 00:08:29 Pineapple kern.info kernel: [ 509.440000] br-lan: port 2(wlan0) entered forwarding state 00:08:29 Pineapple kern.info kernel: [ 509.430000] br-lan: port 2(wlan0) entered forwarding state 00:08:29 Pineapple kern.info kernel: [ 509.340000] device wlan0 entered promiscuous mode 00:08:29 Pineapple kern.err kernel: [ 509.650000] ath: phy0: Could not stop RX, we could be confusing the DMA engine when we start RX up 00:08:29 Pineapple kern.err kernel: [ 509.640000] ath: phy0: DMA failed to stop in 10 ms AR_CR=0x00000024 AR_DIAG_SW=0x02000020 DMADBG_7=0x00006400 Quote Link to comment Share on other sites More sharing options...
