Cannot Connect Between iPhone4S and iPad3 using Cisco 877W Router

12 years ago • updated 12 years ago • 14

Hi,
I am having problems connecting between an iPhone4S and an iPad3 using WiFi, and i suspect it to be something to do with the configuration of my Cisco 877W router, as the app works fine using bluetooth, but is obviously a lot slower. I am attching a copy of my router configuration and would appreciate it if anybody can point out what corrections i need to make in order to allow my devices to be able to communicate using the WiFi.

Hi Andy,
:-) ... its a bit more complicated trying to figure out what your router "sees" by simply looking at its config file.

I tried to find the PDF user guide, on the Cisco site, but could not, hoping that shows the settings in a graphical way, with tabs to press so each section can be examined separately, but if you can view these two posts, showing you what to look for, you may be able to figure it out yourself, looking thru your settings options.

It's possible, Enrique, or Amber may already be familiar with this router.

If not, you'll at least have a idea what you want to ask, for more help from Enrique, Amber, or other customers, who may volunteer an answer.

This post shows where on the iDevice to look, and what generally to look for.
https://getsatisfaction.com/photo_tra...

This next post, with my gvdid1 name in the post near the end, mentions what needs changing in the router, in case another router with the same default name and/or IP# group exists in the area, so you'll know when it's your router(network) you're actually on.

Hi gvdid1,

Thanks for your reply, both my devices are attached to the same network as I have an SSID which I have named W1F1-22 and I used to have it hidden, until I have been trying to fault find my problem, and therefore I can also confirm that they are both picking up an IP address in the same subnet. I am certain that this issue is nothing to do with the app and all to do with the Cisco 877w router itself. I was hoping that someone else may have been using the same router successfully.

12 years ago

Yes, very possible it's a setting in the router, blocking normal connection.

Several things you can look for are ...
- The MAC address filter being on that stops unlisted (allowed) device MAC addresses form connecting.

- Having "Filter Internet NAT Redirection" checked ON ... in your routers settings
(this is the FIREWALL setting of most routers)

I mention all this, and more, in another post ... Here ...
http://getsatisfaction.com/photo_tran...

Enrique may know this router, but if not, and you have the Owners Manual (PDF) you could upload it to RapidShare.com for free, so he can view it if he's not familiar with the settings.
(or send it to him at his eMail address, he'll tell you where if needed)

One extra point, make sure the App screen remains showing on the iDevice's while you're trying to connect to each other. - If you switch to another screen, on one of the devices, before the transfer starts, the other device will not see the connection address showing in the App screen.

12 years ago

One extra question I forgot to ask you ...
Do you get an IP:port address or device name of the iDevices showing at all, on the App, or is it saying no devices found using the WiFi option?

If BlueTooth works, I agree with you, so too should WiFi, and the router may be blocking it, some how.

12 years ago

I do get the sending device's (iPhone) name show up on the receiving device (iPad3) but then it times out when it tries to contact the sender and you get an error message saying "could not contact the sending device"

12 years ago

It may be a firewall issue with the router.

Can you see the exact IP:port it's using on each device? ... Not just the name.

... if you reverse which one is the sender, you'll see the others IP:port address, too, not just the device name.

I wanted to confirm something.

12 years ago

Hi gvdid1,
On the sender I can see both the name and the IP:port (8080) and the name and on the receiver I see just the name of the sender.

12 years ago

Hi Andy, yes only one side (the sender) will show its IP#(and):port combination, but I was hoping you'd also mention the IP address #'s as well, so I can see if it looks like it's connecting to a valid IP#, or a "limited connectivity" address.

Also, when you reverse the device that is sending to the other one,
... what that IP# is on that other device that's now sending

It should start with http://
then the IP# groups (4 total groups, with the dots between each)
then the port :8080

I'm curious if they match the first 3 IP # groups on each device, and what they are.

12 years ago

Hi gvdid1,
One of them has the IP address 10.10.10.2 and the other has 10.10.10.3, I am using a /29 (255.255.255.248) subnet mask and they are both connected to the same WiFi ssid.

12 years ago

Hi Andy,
Yes, it seems they are at least connected to the same network.

But I'm suspicious of the IP numbers themselves.
I'm not sure, but I've always been told the internal IP addresses with 10.10.xxx.xxx
were corporate type addresses, set to be limited, and private.
(limiting access between connected devices to {within} that network.)

I'm thinking this is what Enrique was saying to others, owning certain models of Cisco routers, that the router can create a "guest" network that's limited between devices, and a standard network, with all functionality.

Normally, a standard network IP group would start with 192.168.xxx.xxx

If you have any documentation for the router, that explains the settings, or if you can look around your Graphic User Interface web-browser access to its settings, search for network types that this router can create, or privacy settings for the network created already, and maybe you'll find some help text within, or actual setting(s) dealing with a Firewall, or Privacy Tab screen.

When Enrique, or Amber returns, they'll be able to check my "theory" if they're familiar with your Cisco model#.

But, if you have a PDF of your User Guide, ... that would be easier, ... to simply look-up the features and see if I'm right... Or just upload it for me or the others to view, and help with the settings.

Hey Andy,
I found some info on the Cisco site that may help you setup the router Firewall, and some other info regarding that router.

It seems it may also have a built-in VoIP ATA. Which means you may have an included way to attach standard phones to allow the router to connect them for Internet Phone service, from SIP providers.

***Edit***
I may be wrong about the built-in ATA. ... When I saw it mentioned ...
ADSL over POTS , I thought it meant it connected to Plain Old Telephone Systems (POTS) by VoIP SIP, but realize now it's a DSL modem connection over normal phone lines. (I still may be wrong, this is why getting the actual Owners Manual is important) ... :-) ...
**************************************

Anyway, I found a PDF showing some Firewall aspects that the router has, and I may be correct about the limited access it defaults to.

They call it Intrusion Prevention Services (IPS) and Content Filtering.
In addition to the Zone-Based or CBAC Firewall options.
There's a PDF about it ... Here ...
http://www.cisco.com/en/US/prod/colla...

Also, on the main web-page showing that PDF, there are Flash-Based videos showing how to configure the Firewall, and other settings. The iDevice doesn't have Adobe Flash, so you'll need a real computer with Adobe Flash player to view it.
http://www.cisco.com/en/US/products/p...

Cisco has software links to assist, at the links near the bottom of the page ...here...
http://www.cisco.com/en/US/prod/colla...

There may also be software updates you can download there, to make sure you have the latest firmware on that router.
It's near its "end-of-life" for Cisco support, so get what you can, now, before they stop support for it.

This Router is very nice, but may take some time to setup the way you need it.
It is, in fact, a Corporate Router. :-)

Hello Andy, gvdid1,

I'm sorry to enter the discussion a bit late. Looks like you've been trying somethings to get it to work. I just did some quick research about the cisco router and it seems that is quite a sophisticated router with lots of configuration parameters. I couldn't find anything very specific but I think it should be something quite simple to enable to allow communication between devices connected to it. When the devices can't communicate between each other it means that the routers "isolates" each device and prevents traffic to go from one to another directly. I found couple of links that may be helpful on the Cisco website:

https://supportforums.cisco.com/threa...

https://supportforums.cisco.com/threa...

I'm no expert on configuring cisco routers so I'm afraid that I can provide little help with this. I hope the links are useful somehow, I'll try to do some more research and I will post something here if I find something useful.

Kind regards,

Enrique

Hi gvdid1, Enrique,

I have had a look at the various links in your posts and tried numerous changes to the configuration on my router. I have even tried changing my private IP address range from a 10.10.10.0/29 to a 192.168.1.0/29, not that i thought for one minute that this had anything to do with it, but unfortunately I still haven't managed to get it working using my Cisco router. I have however proved it to work with a Thomson wireless router, at my work, so as originally suspected I know that the issue is with the Cisco configuration and not the App.

Thanks for all your help.

Hi Andy,
Have you looked at the section of the PDF showing the Firewall / Privacy settings area within the router? That's where I'm thinking the adjustments may be to solve this for you.

You can always do a router reset, by pressing any 'reset button' or issue of reset command, that could put the router back into factory settings specifications, as a last resort, if all else fails. Maybe that would remove some limits between device to device connections.

But I still think its a Firewall / Privacy issue, because the PDF mentioned being able to 'edit' the settings in that area.

As for the 192.168.xxx.xxx instead of the 10.10.xxx.xxx
I meant if the router set it by itself, back to 192.168.xxx.xxx,
- ... the 10.10.xxx.xxx - was an indication it was adjusted for corporate privacy between devices within the office environment.

Manually 'forcing it' into 192.168.xxx.xxx wouldn't do much, if anything, if the original privacy limitations were still in-place.

If you can look around the web-browser access area, within the privacy, or Firewall sections, you may see something that mentions connections between devices, on the 'local' area network. (LAN)

If you can find the Owners Manual PDF, either on the Cisco site, or a search-engine listing, this is your key to finding detailed information of all its settings, and your 'best-bet' on correcting this issue.

At least you know the router at work does connect, and the App transfers between devices, so you're right, it's a setting within this Cisco Corporate router holding it back, at home.

I really feel bad I can't offer any more help to you, in this situation.
