Looks to have been an MTU problem (which was on my to-do list [but forgotten]), configured for 1452 on both the ATM and FastEthernet interfaces on the 1801 and FastEthernet on the UC520, all OK for the past 24 hours. Thanks for the assist!

I recently purchased a UC520W for use at home to replace an 877W, would like it to do all the front-end stuff, NAT, firewall, PPPoE, voice. Have installed a 1801 in front of it to bridge ADSL to Ethernet (almost), but having some issues. 1801 config: ----------- no ip routing ! interface ATM0 description OUTSIDE no ip address no ip route-cache no atm ilmi-keepalive pvc 8/3 vc-hold-queue 1024 encapsulation aal5snap exit bridge-group 1 no shut exit ! interface FastEthernet0 description INSIDE no ip address no ip route-cache speed 100 full-duplex bridge-group 1 no shut exit ! bridge 1 protocol ieee The UC520W is doing the PPPoE negotiation fine, so the 1801 is bridging (I've tried an 877W as well), I can ping out from the UC520 and attached PCs OK as well. But when it comes to email and web surfing....no joy. Replacing the 1801 with a dumb domestic modem/router in bridge mode works without issue. Have tried bridge irb (both enabled/disabled) and also ip routing (both enabled/disabled), no change. Why am I getting only a partial connection? Any thoughts welcome....and just using the domestic modem/router is the ultimate fall back solution, but I'd like to work out where its failing if I can.

i had the same prob with speed on my old ADSL1 link, it got flakey and would fully reset the link (carrier sync lost) anywhere between 7.2 and 7.5Mb/s, kept my d/l speed to 7.0Mb/s or under and I was fine however this prob will keep carrier sync, but drop connection just doing normal web browsing/mail retreval, no heavy d/l usage. had a connection loss earlier today, just normal pc background activity, no usage at all....weird... any debug logs I should be looking at more closely to determing why the ATM int is going down?

the router is configured for local time, sync'd via ntp, sh clock is giving the correct local time.

Hi, I've attached the normal running and down sh tech logs as requested. Though my ISP does not supply preconfigured modems, we can buy a modem from them and configure it with supplied/online instrustions, or supply our own. My D-Link had been up for over a week (purchased to prove an ISP fault recently), while the 877 went down about 4 times yesterday. This problem has been on going for a few months, but as I've only been home the occasional weekend in the past 6 months I could (sort of) live with it. Cheers, Dave

I am running an 877W in the home that for the most part works fine, however after being connected for a variable amount of time I partially loose my DSL connection. Line sync stays up, but the traffic is lost. A shut/no sut of the atm or dialer interfaces does not resolve the issue, only a reload or power down/up will fix the prob short term till it happens again. Am currently running advipservicesk9-mz.151-3.T1, but have also rolled back to advipservicesk9-mz.124-24.T5 which has the same issue. Have tried a 857W with the same results. So ruling out IOS and hardware, its pointing to a config issue. It has also only been an issue since changing from ADSL1 to ADSL2+. interface ATM0 no ip address no shutdown no atm ilmi-keepalive exit interface ATM0.1 point-to-point pvc 8/35 pppoe-client dial-pool-number 1 exit exit ! interface Dialer0 ip mtu 1452 ip address negotiated ip nat outside dialer pool 1 dialer-group 1 encapsulation ppp dialer idle-timeout 120 dialer fast-idle 20 ppp authentication chap callin ppp chap hostname <hostname> ppp chap password <password> exit ! interface BVI1 ip nat inside exit ! bridge irb bridge 1 protocol ieee bridge 1 route ip ! interface BVI1 ip address 192.168.1.1 255.255.255.0 ip virtual-reassembly exit ! interface Vlan1 bridge-group 1 bridge-group 1 spanning-disabled exit 000066 "ATM: PVC removed, ATM0.1 VCD 1 (8/35)" 000067 "Vi1 PPP: Missed 5 keepalives, taking LCP down" 000068 "Vi1 PPP DISC: Missed too many keepalives" 000069 "PPP: NET STOP send to AAA." 000070 "Vi1 IPCP: Event[DOWN] State[Open to Starting]" 000071 "Vi1 IPCP: Event[CLOSE] State[Starting to Initial]" 000072 "Vi1 CDPCP: Event[DOWN] State[Stopped to Starting]" 000073 "Vi1 CDPCP: Event[CLOSE] State[Starting to Initial]" 000074 "Vi1 LCP: O TERMREQ [Open] id 2 len 4" 000075 "Vi1 LCP: Event[CLOSE] State[Open to Closing]" 000076 "Vi1 PPP: Phase is TERMINATING" 000077 "Vi1 LCP: Event[DOWN] State[Closing to Initial]" 000078 "Vi1 PPP: Phase is DOWN" 000079 "NTP Core (INFO): system event 'event_clock_reset' (0x05) status 'sync_alarm, sync_unspec, 8 events, event_peer/strat_chg' (0xC084)" 000080 "NTP Core (NOTICE): Clock synchronization lost." 000081 "Di0 Deleted neighbor route from AVL tree: topoid 0, address 220.233.1.45" 000082 "Di0 IPCP: Remove route to 220.233.1.45" 000083 "%DIALER-6-UNBIND: Interface Vi1 unbound from profile Di0" 000084 "%LINEPROTO-5-UPDOWN: Line protocol on Interface Virtual-Access1, changed state to down" 000085 "%LINK-3-UPDOWN: Interface Virtual-Access1, changed state to down" I've tries some changes mentioned here and from other sites, but no success yet...
