I have set up a Switch from the Modem and a Wireless Access Point "D-Link DWL 800AP" and on the Wireless Laptop I can see the network but get This connection has limited or no connectivity .

When I run a ipconfig I have no valid IP Address .


Where have I gone wrong or do I have to use something smarter like a Router ?

Yea, you need a router. The switch will not work.

This is off the Flow u-click troubleshooting page:

Problem
I have two computers and a switch connected to my Flow modem but I am only able to connect with one (1) computer at a time.

Possible Solution
Flow’s Standard modem only gives out one (1) public IP address to the first device detected by the modem (switches are not addressable devices). Any other devices plugged into the switch will not receive a new IP address. To connect more than one (1) device at a time a dedicated Router (Linksys, D-Link or other) is needed.

Problem
I have a switch connected to my modem but I am only able to connect with one PC.

Possible Solution
The Standard modem ‘remembers’ the first device connected to it and will only allow access to this device. It is likely that the modem is remembering a previous device that was plugged into it and therefore refusing to issue an IP to another device. Reset the modem to clear its memory.

How exactly did you connect the router?
You need to connect the output of the flow modem to the wan port on the SMC router. You also need to ensure there is no private ip address conflicts which I don't think would be a problem since the SMC lan address is 192.168.2.1 by default. Some users have expressed that the flow modem is troublesome in that you need to hold the reset button for it to release the old ip lease and give it to the new router you plug in. You will need to check if the SMC router is getting a valid WAN ip so log into the router setup and view the wan status information.

I have the same problem as all these guys except I use an MSI router.

From what I've gathered so far, I must first ensure that the router has a different private ip like 192.168.1.100 and then plug the cable from the modem into the WAN port on the MSI and then run the other cables from the msi to my 2 desktops.

Does the modem automatically act as a DHCP and DNS server with NAT etc?

Should I set my desktops to any particular IP or shuold I just choose "Obtain IP address automatically"?

Is there any extra configuration I have to do on the router?

Any help is greatly appreciated.

Thanks in advance.

Correct as the default ip of the modem is 192.168.100.1

Yes, the router will automatically pull these settings from the modem so be sure not to set the ip as static in the router

Not necessary however if you do make sure to forward your ports properly to get the max functionality from your connection

I would recommend that you config your router for added security

If you are using the RG60SE I can provide step by step for this router if needed. I have a lot of experience especially with this MSI router.

Bossman, yuh really is a boss. Thanks for all the help.

Bossman,

I am a new member to this forum,

I am having difficulties getting wireless connections with my MSI RG54GS2
wireless router and Flow's ARRIS Model TM602G modem.
I have tried resetting the modem as mentioned in Flow's web page help section but to no avail.
I was advised that a static IP address from Flow could help.I am still awaiting there response.

Any suggestions in reconfigure my router settings or any help in solving this problem
will be appreciated.

Thanks,

Patterson.

See why you must read the forums. This is exactly the question I was going to post.

Catch my tail this evening at the office trying to configure the new cable modem to 2 switches and then realise
that only one computer at a time could get on the internet.
Couldn't believe that flow would use this (forgive me if this is the nature of cable modems)
kind of device. Both TSTT and greendot devices can both give out ip addresses to all computers on the network.

There is a wireless router that we use as an access point. Tomorrow I will try that and see.

Yea I believe this is the nature of most or all cable modems, they do not provide network address translation as with the blink modem/router etc. Meaning the modem is only capable of handing out a single IP address which is the public IP address assigned by Flow. When you connect the flow modem to the internet port on the router you can connect your other 2 switches to the LAN ports on that router as well. It is also reported that you need to reset the flow modem when you connect it to a router to refresh the dhcp lease.
Best of luck.

Worked like a charm.
Shut down all computers on the network but that flow modem is something else. Battery backup so it never completely turns off. You have to reset it.

So I plugged it into the WAN port of the router and reset the modem so that the router would get the ip address.
Then started turning on computers one by one and they all received addresses.

Made sure internet was working on them and reconfigured the server address in the router so that if it turned off it was assigned the same ip
based on the mac address. Maybe in the future I will do this for all the computers.

So just to confirm that this is the procedure that works with a flow modem and router.
