876W Router: internet wired but no wireless internet, need help configuring

EH1165305
Level 1
Level 1

For a long time now I try to get my 876 Wireless Router configured but I do not succeed. (I'm just a cisco loving amateur so please respect my poor knowledge)

Problem is that I got the router setup for internet connection but only wired. Now I have a configuration in which I also succeed to make a wireless connection. Only the problem is that the wireless connection does not get to the internet.

Next to some other minor looking problems that will be the main thing!

I tried several helpfull tools as CCP and some sites which gave a Form-template on the internet or a Excel-sheet to fill in. All those did not function for me.

Now I hope there will be someone out there who is willing to have a look at my running-config and give me a helping hand.

Thanks in advance,

Emil

Thanks. Wireless is now working. I have a connection with internet on my connected Iphone.

Strange enough though now wired internet is not working anymore

On the connected console I can ping my DNS from within the console-connection. Also get a addressresolution for www.google.nl. I can ping my Iphone. I can not ping my ISP IP adress though!

On my wired laptop the internet browser does not find google or other addresses. In the dos prompt I can not ping to my own ISP address, no DNS.

What I did was as you suggested bridge 1 route ip and removed "ip tcp adjust-mss 1452" from vlan 1.

Some suggestions left... Would make me very happy

Yep...try:

bridge 1 protocol ieee

See if that gets your wired side working, and you should be good....

HTH, John *** Please rate all useful posts ***

Thanks for your very fast responding as I'm in the middle of the night and have to get up in a few hours. But this is important for me and I hope to solve it with your help.

Unfortunately nothing changed!

I can ping my Iphone yes. But still no internet from the wired connected laptop. I did not see a change after bridge 1 protocol ieee command....

Hmmm.....are you getting an address on the wired side? Can you ping the router at 10.10.10.1?

Also, what port are you connected to? Are you connected to the switch on the router or another switch that's connected to the router? What port is that connected to on the router?

HTH, John *** Please rate all useful posts ***

Sorry about taking so long. Have to plug and unplug on my two routers for connection to you.

I cannot ping out of the laptop to the router. Which I could before I got it wireless.

Tried F0 and after that also F4. Both don't give ping possible.

I have a switch, but for this "exercise" I made the connections directly to the router. The switch is not connected now. The IP address I gave the laptop is 10.10.10.4 and should be ok with DNS, gateway and mask set.

I don't know if it is of interest but I did a sh ip int brief and saw that the BVI1 is not up so I did a manual no shut.

This unfortunately did not solve the problem either and I hope I did not disturb your thinking about the solution.

Here is the output:

yourname#sh ip int brief
Interface                  IP-Address      OK? Method Status                Protocol
ATM0                       unassigned      YES NVRAM  up                    up

Virtual-Access2            unassigned      YES unset  up                    up
Vlan1                      unassigned      YES manual up                    down

And my intervention to get the BVI1 up

yourname(config)#int BVI1
yourname(config-if)#no shut
yourname(config-if)#exit
yourname(config)#exit

See now that is was up but what is down is the BVI1. Don't know if this is important and how to solve....

Sorry. I replied to you yesterday from my phone by replying to the email, but it didn't post apparently.

On the port that you're connected to in the router, change that port to a trunk port. I'm not sure if that will do anything, but that's the only difference between yours and my 871W that I have configured. So, if you're connected to FA0, try:

int fa0

switch mode trunk

Let me know if this did anything. Also, after you do that, if you haven't rebooted you may want to try that as well.

HTH,

John

HTH, John *** Please rate all useful posts ***

Thanks John you did not give up. I went to bed and did not get any messages anymore. So I thought that was it. Problem cannot be solved. Maybe a hardware issue, although strange.

But... you made my day.

After I gave the swithport command, which I will try to undo also later on this day as I have no time at the moment, nothing changed.

Than I did the copy run start and rebootet.

And thanks God I'm online now with the 876W router wired to my laptop! And also my Iphone is still working wireless connected.

You cannot imagine how glad I am

Now I don't know what went wrong and if I should have rebooted earlier on the problem would be solved before the last issues, where you where stonnishing about not functioning after your great help. But anyhow it functions wireless and wired to at the moment.

Later on in the weekend I have some more time and will have a look if I can get my Cisco switch again inbetween as the rest of my computers now is ofline.

Again thank you very much for your great consistent and appreciated help. You earn a goldmedail!

Emil

Message was edited by: Emil Heilbron I did a no switch trunk and now the switch is inbetween again. Maybe I can ask you a last question as I detected that my other computers are not in the range of IP addresses. How can I make some more IP addresses connect to the router? Thanks

Glad to hear it   Sometimes a reboot is all that's needed, especially when nothing else makes sense! LOL! If you would, please rate this post so others can find it if needed.....

Thanks!

John
