Cant ping out - two modems, two linksys, split cable connection

[xeusmaximus]

I have one cable connection that has been split into different parts of the house. I
had a connection on both sections of the house without a problem. Then I lost
connection on one side of the house. I tried to solve the issue by cycling the modem,
and also cycling the linksys that is attached to the modem... reseting...etc... have
done so many things but still cant seem to work.

when I ping 192.168.1.1 it sends 4 packets, and receives 4 100%
however, I cant ping google.com, or ping yahoo.com... and of course it doesnt tracert
either... I am trobleshooting with win2K, so I turned off the zonealarm... still no
connection. I have three laptops, one desktop, and one mega server. Linksys unit is
wifi model wrt54g v1.01.0. Linksys used to have great support, after cisco bought it, I
think support is connected to form letters, and some sorry a55 artificial intelligence.
Whatever they suggested was useless.

then I did ipconfig/all

IP 192.168.1.101
subnet 255.255.255.0
default gateway 192.168.1.1
dhcp server 192.168.1.1
dns server 192.168.1.1

then checked linksys under status section, it gives

IP 192.168.100.1
subnet 255.255.255.0
default gateway 192.168.100.1
MTU 1500

under status>local
IP 192.168.1.1
subnet 255.255.255.0
dhcp enable
start ip 192.168.1.100
end ip 192.168.1.149
---------------------
the other side of the house where internet works flawlessly, the modem is attached to

linksys BEFSR41 v2.00.4, it doesnt have wifi, I did ipconfig/all

IP 192.168.1.100
subnet 255.255.255.0
default 192.168.1.1
dhcp 192.168.1.1
dns server 66.70.160.20
dns server 66.70.160.21

then checked linksys under status section, it gives
login type dhcp
IP 79.90.146.75
subnet 255.255.255.0
default gateway 79.90.143.1

I can ping localhost(127.0.0.1)

please help

thank you

I have one cable connection that has been split into different parts of the house. I
had a connection on both sections of the house without a problem.

can you make a wiring chart to describe the split, eg
modem---router#1---??

when I ping 192.168.1.1 it sends 4 packets, and receives 4 100%

yea, that's only to the router

however, I cant ping google.com, or ping yahoo.com... and of course it doesnt tracert

then I did ipconfig/all

IP 192.168.1.101
subnet 255.255.255.0
default gateway 192.168.1.1
dhcp server 192.168.1.1
dns server 192.168.1.1

[a] this is the systems view of the router

then checked linksys under status section, it gives

IP 192.168.100.1
subnet 255.255.255.0
default gateway 192.168.100.1
MTU 1500

hmm; looks strange; normally this is a public ip-address
where does the WAN cable on this router lead to?

under status>local
IP 192.168.1.1
subnet 255.255.255.0
dhcp enable
start ip 192.168.1.100
end ip 192.168.1.149
---------------------

this matches [a] above which is consistent

the other side of the house where internet works flawlessly, the modem is attached to

linksys BEFSR41 v2.00.4, it doesnt have wifi, I did ipconfig/all

IP 192.168.1.100
subnet 255.255.255.0
default 192.168.1.1
dhcp 192.168.1.1
dns server 66.70.160.20
dns server 66.70.160.21

then checked linksys under status section, it gives
login type dhcp
IP 79.90.146.75
subnet 255.255.255.0
default gateway 79.90.143.1
static dns1 66.70.160.20
static dns1 66.70.160.21
MTU1500

YEA! That's a public IP setup; you can ping the gateway address as well as both DNS addresses; tracert will work too

under status>local
IP 192.168.1.1
subnet mask 255.255.255.0
dhcp server enabled

again, the system-side of the second router which is good

*****************************
I can ping localhost(127.0.0.1)

of no value

how?

ISP cable split into two section of the house

ISP cable > modem - motorola sb5101 surfboard > linksys WRT54G - wireless with 4 ports
ISP cable > modem - rca digital broadband dcm425 > linksys BEFSR41 - 4 ports (dont have
wifi)

Linksys suggested I cascade the routers. I told them it is in the other side of the house, and it is not an option really.

Then, they suggested to use befsr41 with wet54g which has bad reviews, then they suggested WAP54G with wrt54g , which has another set of bad reviews. I guess linksys cant make bridges, or repeaters. When I asked them if I have to use another linksys product if there are any other options. They said linksys is the way to go.

when I told them it worked for six hours, how come there isnt any way to make it work... they said it wont be reliable/stable ???

Yes, that is the usual approach

Then, they suggested to use befsr41 with wet54g which has bad reviews, then they suggested WAP54G with wrt54g , which has another set of bad reviews. I guess linksys cant make bridges, or repeaters. When I asked them if I have to use another linksys product if there are any other options. They said linksys is the way to go.

Never been totally happy with Linksys, but the approach is viable. I have a D-link DWL-G810 (no longer in production) and it worked well -- search for the newer model

ISP cable split into two section of the house

ISP cable > modem[a] - motorola sb5101 surfboard > linksys WRT54G - wireless with 4 ports
ISP cable > modem - rca digital broadband dcm425 > linksys BEFSR41 - 4 ports (dont have wifi)

btw: both the RCA dcm425 and motorola sb5101 ARE MODEMS and chaining
modem->modem is not possible; The maps should be

• ISP->motorola sb5101 ---
  and ISP -> RCA DCM425 ---
  moving on ...

YEEK! That's the problem! You insist that this actually work previously?
I would expect the ISP to required TWO subscription fees!
.
Which ever path is broken {a?b} think hard to recall which PC was FIRST connected to that modem
remove the router and reconnect that same PC. If this works again, then you need to set the router to
enable MAC Address Mascradaed (see how/why )
