Thread: Connecting SmartAX MT882 to TP-Link WR642G

Hello,

I bought the TP-Link WR642G wireless router to connect it to my existing Huawei SmartAX MT882 modem.

I wired up the connections okay, but can not get the router to connect to the internet.

Some of the things I did while connecting the router:

I chose PPPoE as connection type, keyed in the login & password provided by the ISP.

I assigned the router IP address at 192.168.1.3

I tried setting TCP/IP settings to "detect automatically" as well as with specific gateway and DNS settings (as provided by BSNL).

But with none of these methods could i successfully connect to the internet.

Note that I never tried the wireless yet. I am still trying the wired (LAN)connections.

thanks in advance for some help.

best regards
Nagendra

Firstly decide which one device u need to connect to the internet. Either the wireless router or the wired router.

U can configure the wired router to connect to the internet, just like u used to do in pppoe mode. Connect the wired and wireless devices using a cable.Then disable DHCP on the wireless router. The wireless router will act like a hub in such cases and u can connect multiple pcs.

Note that the cable connecting both devices should be crossover cable.

SmartAX MT-882 ADSL MODEM MENU


After you get connected to internet with mT882
http://www.tp-link.com/english/soft/200865140530.pdf
please download manual for settings.
I have downloaded the manual. for reference

Checkout http://www.indiabroadband.net/bsnl-b...er-wrt54g.html (Setup of ADSL Modem/Router UT-300R2U with Linksys Wireless Router WRT54G) It might be of help too..

Hi again,

thank you for the information.

I am trying to assimilate the info at all the links but struggling with a few basic pieces of configuration i need to get right.

let me ask you all the questions:

1. On the modem (MT 882), do i need to change any settings to make it work with the router?
- first. do i need to change the WAN type? (presently it is PPP and Connection type PPPoE)? Do i need to change it to RFC2684Bridged or RFC2684Routed?

- second. the DHCP settings on my modem are:
DHCP Server Enabled
Starting IP Address 192 . 168 . 1 .
Ending IP Address 192 . 168 . 1 .

Does any of this need a change? Esp do i leave DHCP enabled on the router?

2. On the Wireless router (WR642G), do i need to change the below settings?
- Do I disable or enable DHCP?
- What is a good IP address to assign to it? (say 192.168.2.1)?

Thanks
Nagendra

The WAN type present in 882 is showing the technical details of your BSNL connection. No need to tamper with it as your connectivity to BSNL will be affected.

If u want to connect the wireless router to the wired router and to make the wireless router act as a hub, u need to disable DHCP on the wireless router. IP address should be assigned manually to each and everyone of the PCs connected to the wireless router.

If the DHCP is disabled on wireless router the third question doesnt crop up.

IP address of 882 must be 192.168.1.1
IP address of WR must be 192.168.1.2
IP address(es) of PCs connected to WR must be 192.168.1.3, 192.168.1.4 etc etc

Please post if the doubts are still present.

Hello again,

I haven't fixed it yet.

Let me present to you the settings I observe and let you review them and find any trouble with them.

The WR settings are as below:

Does this point to any configuration errors?

Thanks again.

Ok, did u check the 882? Is it getting connected to BSNL? Does the mentioned values include the 882 status too?

No, all the mentioned values are from the WR. In fact, if I connect the WR, I am no longer able to ping the MT. that is, i can not ping 192.168.1.1 anymore.

The MT 882 if connected directly to the laptop, the laptop is connecting to the internet.

Which settings of the MT 882 would you like to observe?

i can post them right away.

Sorry for the delay in replay, power failure in here. Please answer the following queries.

1) What is the purpose of WR? U want to access net utilizing wifi in laptop?

2) How many PCs or laptops are involved?

Oh well, i want to be able to access the internet from 2 laptops at home. That is the main reason for the wireless router.

For testing, i am still connecting the laptop to the wireless router through a LAN cable.

Thanks
Nagendra

I am not sure I made my response clear.

Yes, I want to be able to setup Wifi connectivity to the internet from both laptops via the wireless router.

For now, I am connecting the laptop via LAN cable to the router, just to ensure i first establish connectivity before trying the wireless mode.

Ok, so its better to eliminate the 882 from the scene. And configure the WR to work with BSNL in pppoe. Once WR is successful in establishing a connection with BSNL, then u can easily configure both the laptops for wireless access.

I dont think I understood what you meant.

The WR 642G is a wireless router only, can not act as the modem.

So, I will need to connect my MT 882 modem to the BSNL phone line. Its Ethernet output goes into the wireless router. The router has both wifi and 4 wired ports (LAN ports). I have connected one of the ports to the laptop.

Can you explain what you meant by "eliminating MT from the scene"?

thanks

The wireless router which u mentioned is not just a wireless repeater. It can be configured to do the functionality of the MT882 ie it is a router. So once we get the wireless router to connect with BSNL, then its easy as a pie.

Edit : My mistake, it does seem to be a wireless repeater. Just downloaded the spec sheet from the website. Use the guides found in http://www.tp-link.com/support/downl...=1&m=TL-WR642G to configure the repeater.

No problem. So assuming i will need to keep the MT882 connected to the BSNL phone line, and connect the WR to it, what would be the expected settings on the WR?

I posted the settings on the WR earlier, would any of them need to change?

Well I just saw your update with the links to the manuals, let me see what i find in them.

thanks again for your continued help
Nagendra

Hmm. the link you sent indicates three versions (v1, v2, v3) of the product, and tells how to discern the version you have. I find that my version is 3.5! No such version is reported at their website!

I am not sure I want to do firmware upgrade etc since that might just make matters more confusing.

Now that you know what I am trying to do, can you find any obvious faults with my setup parameters specified in the WR settings?

Try the v3. Since v3.5 must have come after v3, there must be minor changes only. This link http://www.tp-link.com/english/soft/200865140530.pdf may also come handy.

1.Confirm, you can
connect to Internet with MT882 modem.
either laptop.
Go step by step.
2.Post ipconfig/all data of one laptop .
3.Then download the manuals as mentioned earlier.

4.I don't have the wifi router
manual 86 pages PDF format and downloaded the same
for reference and guidance to you.

Para two:

5.Wireless settings also will have to wait.
6.From the WIFI router LAN1 to laptop1 / or laptop2 to be tried.

7.Then finally WIFI.
8.Then security keys.
9.Plenty of guides available. steps are almost same except the pages may look different and may be with addl facilities.
Your WIFI router seems to be Linksy's or Dlink's type/. equivalent.

That was what which had got me confused in the first place. Its not a wireless router. Its just a wireless repeater. Means we have to supply the output of MT882 as input to this wireless device and it will transmit using wifi. Just like the ones found in offices.

I would post the MT 882 settings tonight and continue the investigation in the night today. I will be able to dig into this around 9:30pm tonight.

thanks

Make sure to take a sneak peek into the last pdf file provided by me. I myself have downloaded the pdf and its pretty straightforward. U just need to get the MT 880 working. The rest of configuration details are given in the manual. Do accordingly please.

Hi there, my MT 882 (the ADSL modem) is working fine. As you indicated, i think i should not have to tamper with its settings. Problem seems to be the settings on the WR only.

I will anyway post the MT 882 settings later once I am home, just to be sure.

I read a lot of the pdf pages yesterday, i will print out parts of it and follow through it accurately. I will probably first hit the reset button to restore factory defaults.

thanks

Hi, i could be late getting home, logging in and checking out the settings of the WR tonight. I will get to it but will be late. By tomorrow morning, you should see a post of the MT882 settings and other things i will try. Hopefully i will get this to work tonight :-)

thanks

The MT882 seems to be working fine. I would suggest switching the ADSL modulation from ADSL2+ to G.DMT.

Also like mentioned by essbebe please enable DHCP in the MT882.
