If it's the rain all you can do is wait for things to dry out, if it doesn't fix itself then maybe call your isp and they can send out a chorus tech. But try a different modem first, they're less than $100, vodafone might evem send you out one free if you sign a contract.

IMHO a little excessive in the firewalling .. :) The little cisco's (even the larger ones) could max out in CPU/Thuput with excessive inspects You are dropping packets a little due to packets being out of sync.. increase them a little ip inspect tcp reassembly queue length 1024 (or something not so large) ip inspect name WAN_FW appfw WAN_FW <-- a little strange.. remove it .. unless you have appfw defined called WAN_FW ??? Yes you do have a low connection rate and maybe errors? do you have interleaving on/off? (which might fix the errors if you do) . Tried looking at getting your line checked?

LennonNZ: IMHO a little excessive in the firewalling .. :) ... call me paranoid... I like to see what's going on, plus the router can handle it. Session audit trail is enabled Session alert is enabled one-minute (sampling period) thresholds are [unlimited : unlimited] connections max-incomplete sessions thresholds are [unlimited : unlimited] max-incomplete tcp connections per host is unlimited. Block-time 0 minute. tcp synwait-time is 30 sec -- tcp finwait-time is 5 sec tcp idle-time is 3600 sec -- udp idle-time is 30 sec tcp reassembly queue length 16; timeout 5 sec; memory-limit 1024 kilo bytes dns-timeout is 5 sec Inspection Rule Configuration Inspection name WAN_FW icmp alert is on audit-trail is on timeout 10 inspection of router local traffic is enabled fragment Maximum 256 In Use 0 alert is on audit-trail is on timeout 1 dns alert is on audit-trail is on timeout 30 ddns-v3 alert is on audit-trail is on timeout 30 ftp alert is on audit-trail is on timeout 3600 ftps alert is on audit-trail is on timeout 3600 Application Policy name WAN_FW Application http strict-http action allow alarm content-type-verification unknown-type match-req-rsp action allow alarm port-misuse tunneling action allow alarm transfer-encoding compress action allow alarm transfer-encoding identity action allow alarm transfer-encoding chunked action allow alarm transfer-encoding gzip action allow alarm transfer-encoding deflate action allow alarm audit-trail is enabled http alert is on audit-trail is on timeout 3600 https alert is on audit-trail is on timeout 3600 esmtp max-data 20000000 alert is on audit-trail is on timeout 3600 imap alert is on audit-trail is on timeout 3600 imap3 alert is on audit-trail is on timeout 3600 imaps alert is on audit-trail is on timeout 3600 pop3 alert is on audit-trail is on timeout 3600 pop3s alert is on audit-trail is on timeout 3600 ntp alert is on audit-trail is on timeout 30 sip alert is on audit-trail is on timeout 30 sip-tls alert is on audit-trail is on timeout 30 snmp alert is on audit-trail is on timeout 30 snmptrap alert is on audit-trail is on timeout 30 rcmd alert is on audit-trail is on timeout 3600 syslog alert is on audit-trail is on timeout 30 syslog-conn alert is on audit-trail is on timeout 3600 tcp alert is on audit-trail is on timeout 3600 inspection of router local traffic is enabled udp alert is on audit-trail is on timeout 30 inspection of router local traffic is enabled so queue length is 16 (assuming this is the default as I've never changed it)... after using this router for going on 5 years would it be safe to assume (never safe to assume... lol) that this is a cabling fault or should I up the queue length? Thanks for your assistance LennonNZ, it is much appreciated :)
