Hello all!
I've just recently upgraded a Cisco 877 to 887W router.
I basically copied most of the config across to the router with no problem.
ppp chap hostname and password all ok. ATM and Dialer1 interface comes up.
The problem I'm having is when I open Internet Explorer up, default homepage is Google. Google loads up fine, type a search is fine but when you click on the link or type URL, for example BBC News or Sky Sports, it takes a long time to load or times out (Page cannot be displayed)
DNS servers configured on Cisco router are:
8.8.8.8 and Virgin's DNS servers.
NSLOOKUP in cmd prompt it returns IP add no problem. however in web browser it fails except for Google.
However, with the same config on a 877 everything works perfectly... any ideas guys?
Cisco 877 running 12.4
Cisco 887 running 15.0
Thanks in advance

Hi Jeffy,
Please remove the highlighted lines below.
interface ATM0
ip tcp adjust-mss 1452
--------------------------------------------
Please copy the highlighted line on the interface wlan-ap0.
interface wlan-ap0
ip tcp adjust-mss 1452
Please update me.
thanks

Guys, I think I resolved this the model we're using doesn't support ADSL only supports ADSL2/ 2+ (
CISCO887W-GN-E-K9)
Can someone confirm this? Cisco release notes doesn't state this.
if it doesn't support ADSL then why does the ATM/ Dialer interface come up and establishes ppp connection with provider.
And why does Google homepage and search function works?
Thanks

Try with clean configuration and see...
interface ATM0
no ip address
no atm ilmi-keepalive
pvc vpi/vci
pppoe-client dial-pool-number 1
!
interface Vlan1
ip address aaa.bbb.ccc.ddd yyy.yyy.yyy.yyy
ip nat inside
ip virtual-reassembly in
ip tcp adjust-mss 1452
!
interface Dialer0
ip address negotiated
ip nat outside
ip virtual-reassembly in
encapsulation ppp
dialer pool 1
ppp authentication chap callin
ppp chap hostname xxxx
ppp chap password yyyy
!
ip nat inside source list 1 interface Dialer0 overload
ip route 0.0.0.0 0.0.0.0 Dialer0
!
access-list 1 permit any
Good Luck.

Actually it supports all types of ADSL.

Hi All,
Thanks for this post the ip tcp adjust-mss 1452 (on the dialer interface) setting solved this problem for me on 2 new Cisco 887 routers.
Thanks for your help,
Eoghan
