Cannot Connect To Multiplayer Servers

Re: Cannot Connect To Multiplayer Servers

Hmm, take a look at his guide, especially at point 10 and 11: http://www.wikihow.com/Convert-Links...n-Access-Point
All at your own risk, of course

As for the modem, I get lots of hit like this: http://curacaoconnected.com/the-uts-...-easy-to-find/ , but I assume you have already tried them?

Re: Cannot Connect To Multiplayer Servers

The only thing that uses the wired connection is the desktop PC. There are two laptops, a PS3, and an ipodTouch that connect via the wifi. I cannot change any settings on the Comtrend modem/router as the ISP changed the login to the admin panel.

The modem is Comtrend ct-5374
The router is Linksys wrt54g v8

Re: Cannot Connect To Multiplayer Servers

Yeah, I'd say that is your problem. You are double NATing, which will cause all kinds of issues.

What we do to work around that is put the ISP router in Bridge mode and setup the main router to do everything else. Of course, your main router has to have the PPPoE features to do all that.

The other thing you could do is remove the second router and only use the ISP router.

OR, depending on your setup, if you use the Linksys for Wireless, set it up for the wireless portion only and plug everything else into your LAN connection.

Unfortunately, a lot of this could be confusing and very technical. I dont know how comfortable you feel with any of this, so what you do is get one of your geeky friends to read this post and if they fully understands it, ask them to do it.

I have to use their hardware, and the default username and pass for it is not set to the default. (They told me that it costs money per month for them to turn on the wireless router functionality of it). So how can I make my router an access point? maybe that will work.

It depends on the router. But we might be able to look it up if you can tell us the exact name of your router

Re: Cannot Connect To Multiplayer Servers

I had to use an ISPs router together with my own router for a while, its a nightmare.
The only thing that will make you happy in the long run is to get a modem-only solution from the ISP and then use your own router.

But it in the meantime, you should see if your own router can be set up to work as an accesspoint, that will disable all the reduntant router functionality like firewall, DHCP and NAT.

Doubling up on routers is probably an issue, if not they only issue.

If you know the exact make/model of your ISP's modem you may be able to get into it with a default username/pass. A quick Google search yielded this, I don't know how accurate or up to date it is: http://www.answersthatwork.com/Downl...sys_Others.pdf

Good God, I've never heard of so many chain reaction issues before with an ISP/router. If your ISP forces you to use the modem/router they give you then I'd probably call and ask for a new model or replacement modem if I were you. Say it's broken or something, I don't know.

If you are NOT forced to use their modem/router, you may want to just get rid of that particular modem completely and get your own that is a modem/wireless router hybrid. Yeah, it'll cost you money but it'll probably work out a lot better in the long run. I know my ISP, Verizon, forces you to use their hardware otherwise the net tends to not work at all, which sucks.

Re: Cannot Connect To Multiplayer Servers

Just discovered something, it turns out the modem here that the ISP installed also works as a router. It was installed when I was not living here to replace the old modem since the ISP updated the network in the neighborhood. (comtrend ct-5374 multi-dsl cpe)

So that means I am connected from the isp to the comtrend modem/router and now to the linksys router. It is obviously an issue of the two devices talking to one another. The issue is, how do I resolve this? I tried running the comtrend as a router but the wireless wont function on it for some reason, I cannot login to the device either as the login password do not work. So is it an issue between the two devices communicating? This has now happened with two routers connected to this comtrend.


Called the ISP. They had me input the DNS and ADNS numbers instead of it trying to obtain automatically. I attempted to connect to BF3 and it connected, (so i thanked them and hung up), I thought hmm maybe this is just a whim and it connected because it has before randomly, I attempted again to connect and bam doesn't work. Also found out my internet is a PPOE (it used to be static when I lived here last year before the upgrade)

Re: Cannot Connect To Multiplayer Servers

Okay today's attempt. I took the Linksys router I was using at my old house (which ran bf3 just fine) and connected it to the internet here. Again the game will not connect via the router but will just fine on the modem. Now this is just confusing.

Re: Cannot Connect To Multiplayer Servers

Okay looks like it might be as simple as blocked ports. But the issue is, I try to unblock for example port 443 in my router but it still shows the port being blocked, this leads me to assuming that the ISP is blocking the ports?

http://www.yougetsignal.com/tools/open-ports/ I went here and scanned the ports needed for BF3

Only 80 is open.

A bit late, but as far as I can see that website just checks what ports you have running on your own PC.
The BF3 specifications seem to be a bit unclear, but I should think a lot of these ports are outgoing, e.g 80 and 443 are http and https, not something you would expect your game client to be listening on, but both are required to talk with the battlelog server.

If you want to see what ports your own system are currently listening on you can type netstat -an | more
Other tools like zenmap ( http://nmap.org/zenmap/ ) can scan a remote server for open ports, but that is rarely popular with the server owners.

Re: Cannot Connect To Multiplayer Servers

It only has an enable and disable feature on the routers firewall. disabling it does not help.

Re: Cannot Connect To Multiplayer Servers

Weird. Your router have any firewall/security settings you can maybe lower? Or try a different router if possible?

Re: Cannot Connect To Multiplayer Servers

Okay looks like it is the router, just did a direct to modem connection on the desktop PC and it connected right away.

Re: Cannot Connect To Multiplayer Servers

for some reason it didnt appear on the connected devices list
okay it was point 2 found it via the routers security login log and confirmed via the ipconfig.
Put it in the DMZ still doesn't work, same connection error.

Re: Cannot Connect To Multiplayer Servers

Your router page doesn't have a status screen that lists connected devices?

If not, open up a cmd window (Start > cmd > hit ENTER)

Type in "ipconfig" without the quotes.

It should tell you your network IP there. Something like 192.168.1.36 or whatever.
