how to connect SmartAX MT882 and WRT54GC
in [Wireless]

From: RJK on 2 Sep 2009 04:01 Having bought a Linksys WRT54GC that I assumed had an adsl modem in it, as it was described on ebuyer.com as being "3 units in one," and after fighting with it for a while - it seems that there is no adsl modem in it, also there is no PPPoA option in its' settings ! So, have been trying to connect TalkTalks "free" Huwei SmartAX MT882 http://www.practicalpc.co.uk/reviews/hard/comms/smartax-mt882.htm to this http://www.linksysbycisco.com/UK/en/products/WRT54GC with no success. Not sure what the blue rj45/"Internet" port on the rear of the WRT54GC is for ? ...instruction manual says it's for DSL or Cable ! ....have only ever seen a rj11 port for adsl/broadband signal, on "home gateway" units such as my WAG354G. Anyhow, seeing as there seems to be no adsl modem in this WRT54GC unit, and will have to connect it to SmartAX MT882, to get internet into main PC and off to a wifi enabled ADVENT 6651 laptop - I have several hundred questions, .....having never really understood how gateway and ip addresses relate to each other. I know, I know, it's simple if you know how but, I've never been able to grasp what goes where ! Does DHCP have to be switched off in one of the units, if so which ? .... bearing in mind that the Huwei only has one rj45 port which will have to be connected to one of the four yellow rj45 ports on the rear of the WRT54GC ? ...didn't get anywhere connecting Huwei rj45 port to Linksys blue "Internet" rj45 port ! i.e. Can the Huwei's DHCP dish up IP addresses for PC's connected to the Linksys's 4 (well....3 available), rj45 ports ? Does UPNP need to be switched on ? Does the DHCP address range have to not overlap, even if DHCP is switched off in one of the units ? Which mode does the WRT54GC need to be in ? Automatic Configuration - DHCP Static IP PPPoE PPTP L2TP ....and since reflashing it "HeartBeat" ? !!!! ....any help hugely appreciated TIA regards, Richard

The MT882 is a combined ADSL modem and router. The LAN side of the router consists of an Ethernet connector and a USB connector, for a total of two computers. You don't have to use the router in the MT882. There are also some bridged modes of operation. It is possible, if you selected the "pure bridged" mode, that the WRT54GC could deal with the PPPOE from the LAN side of the MT882. I would start, by verifying that the MT882 works with TalkTalk first. In this setup, the talktalk account and password, are stored in the MT882. This would prove the ADSL is setup and enabled at the telco. "Setting up your Huawei SmartAX MT882 modem/router" http://www.talktalk.co.uk/help/questions/NET_01_07 If you attempt to connect the MT882 to the WRT54GC, and run the MT882 in bridged mode, then the TalkTalk account and password would be stored in the WRT54GC. You could connect a computer to one of the four wired LAN ports on the WRT54GC and use the web interface on the WRT54GC, to set up the PPPOE details. The only other tiny detail, is whether a straight thru or crossover Ethernet cable, is needed between the MT882 and WRT54GC. My suspicion is a crossover cable may be needed. The cable provided by TalkTalk, for use in their expected mode of operation, could be a straight-thru cable, as they're expecting a computer to be connected to the Ethernet port on the MT882. <<< wireless / ---- RJ11 --- MT882 --- Ethernet ----- (Blue=WAN_port) WRT54GC ------ LAN1 (Crossover ------ LAN2 cable ?) ------ LAN3 ------ LAN4 Anyway, you've probably got this all running by now. There are likely some forums, closer to home, that can help out. http://www.talktalkmembers.com/forums/ http://www.pcadvisor.co.uk/forums/index.cfm?action=showthread&threadid=342550&forumid=1 Paul

User Guide for SmartAX MT882: http://www.talktalkmembers.com/images/downloads/manuals/SmartAXMT882_ADSL_Router_User_Manual.pdf No, the WRT54GC does not have a modem. The "3 units" are (1) router, (2) switch, and (3) wireless access point. A "gateway" such as your WAG354G, has 4 "units" - (1) a DSL modem, (2) router, (3) switch, and (4) wireless access point. Why are you messing around with the Huwei SmartAX MT882 and the WRT54GC? The WAG354G replaces *both* of these units. How and where you make the connection between the MT882 and the WRT54GC depends on how you configure the MT882. In "bridge" mode, the MT882 acts as "just a modem," just translating between DSL signals and Ethernet signals. In this configuration, you would connect an Ethernet cable between the MT882 and the blue rj45/"Internet" port on the WRT54GC, configure the WRT54GC to PPPoE, and supply your username/id in the WRT54GC's WAN configuration section. This is the configuration that I would use. Other configurations of the MT882 have your userid/password stored in the MT882. Again, how you connect to the WRT54GC depends on how the rest of the MT882's settings are configured. If the MT882 is configured with NAT "on" then you ought not connect to the Internet port of the WRT54GC because then you would have a "double NAT" configuration, which generally is undesirable. *IF* the MT882's DHCP server either supplies a range of IP addresses or can configured to do so, then you would connect the Ethernet cable between the MT882 and one of the 4 yellow LAN ports on the WRT54GC. You would then disable the DHCP server on the WRT54GC (you should only have one DHCP server per network) and set its *LAN* IP address to a value in the same subnet but outside the range supplied by the MT882's DHCP server. The MT882 User Guide does not describe how or if its DHCP server can be configured. I would guess that at the very least, it supplies addresses in the range between 192.168.1.2 - 192.168.1.254. If you can't limit the range, set the WRT54GC's LAN IP to something like 192.168.1.200, which is unlikely to be assigned. uPnP can be switched off. If you leave it on and you also have uPnP enabled on your computer, you may (or may not, depending on the phase of the moon) see a "gateway" icon in "Network Connections" that, if it works, will allow you to configure the WRT54GC without having to access it using a web browser. It's not clear what you re-flashed or what your question about "Heartbeat" might be. Some ISPs require a periodic "I'm still here" signal or they will disconnect you. This is what is usually meant by "Heartbeat." -- Lem -- MS-MVP Apollo 11 - 40 years ago: http://www.nasa.gov/mission_pages/apollo/40th/index.html

The Linksys only deals in PPPoE and not PPPoA so you can use the SmartAX device to make the connection with your ISP and the Linksys to distribute the wireless. The two devices need to be on the same network so configure them as follows :- SmartAX - Static LAN ip address (say) 192.168.1.1 - Whatever WAN settings your ISP needs - Switch the dhcp server on and configure the pool to be (say) 192.168.1.50 to 192.168.1.70 - Connect the RJ45 port to a LAN port on the Linksys. Linksys - Static LAN ip address (say) 192.168.1.2 - Leave the WAN settings blank and the WAN port on the device disconnected - Switch the dhcp server OFF - As mentioned above, connect a LAN port to the SmartAX All clients - Set to obtain an ip address automatically - Set to obtain dns information automatically In case any of the clients don't work still, set their default gateway manually to 192.168.1.1 (the smartax device) and the dns server also to 192.168.1.1 Setting the static ip addresses on the routers can sometimes be tricky. Depending on their default settings you might have to temporarily connect them to one of your pc's directly while you change the static ip address. Jim. |
