891w router wifi question

luisbraga22

Level 1

I have a 891w router that I have been trying to get up and running for a few weeks now since I am clueless on the AP side of things. I was able to get the ssid to broadcast and it says " limited connectivity " but i am not able to get to the internet. My ipad, iphone and laptop that connect do get dhcp ip address from my pool as well.

Any assistance would be appreciated on what i am missing as it is not a lot at this point.

did you set the gateway under the ap section

check this link should get you up and running once you have your internet setup correctly on ios side

if you still cant get it post your config il take a look

Mark thanks for the reply I will take a look. Just to be clear i want to do the following:

AP side:

ip default-gateway 10.0.0.1 (ip address is the ip address of the vlan1 i have on the router side?) so in my case it would be :

ip default-gateway 192.168.100.XXX  (this is my internal ip address for vlan 1)

its actually the ip address of the vlan you specify under interface wlan-ap0 in IOS section which is thw wireless vlan , if you set the gateway as vlan 1 it will be thw wired vlan users

***********************************************

IOS Side

interface wlan-ap0

ip unnumbered Vlan4 

interface Vlan4 

ip address 10.0.0.1 255.255.255.0

***********************************************

AP side

ip default-gateway 10.0.0.1

question i am not using vlan 4.. I have vlan 1 configured. this is ok right? i am asking cause i am not sure if wlan-ap0 has a default with vlan 4.

this seems like issue is with bridging of traffic ..following link will guide for this configuration

http://www.cisco.com/c/en/us/support/docs/wireless-mobility/wireless-lan-wlan/116579-configure-technology-00.html

for best practice you should have your wired and wireless vlans seperate it doesnt have to be vlan 4 but i would have it seperatre, can you post the IOS side as well please

Mark I am up and running now. I actually wiped and configured router again. BUT interesting is that i have a 200mb speed coming from isp and i do a speedtest from laptop connected wired into router and only get 32mb download at best. 22-25 on wifi. Any idea? my port is a gig port, my speed is set to auto... think this could be the issue?

891 has a max throughput of 50mb and thats in test conditions every feature you turn on will lessen your throughput that little bit more , your doing quite well i have seen these routers with vpn running drop to 15mb

Glad you got it sorted anyway

http://www.cisco.com/web/partners/downloads/765/tools/quickreference/routerperformance.pdf

if I get a AP and just use the router IOS side without configuring the AP, will this make a difference?

unfortunatly not , if you look at the link i sent it will show the routers that can support that kind of throughput , you might get a couple of more mb with less features on like wireless but you wont reach 50mb never mind 200 with an 891

Mark is there a home router you would recommend? I also have a asa 5505 firewall i will be setting up with a router.

I would look at standard broadband routers if it's just for onnecting the internet, your firewall running aes or vpn will max only support 100_150mbps aswell after packet inspection as it's 5505,an isr g2 1941 would cover you if your staying Cisco but there but pricier than 800s

default gateway did not work here is mt show run on AP side:
