[Solved] Some Devices Not Connecting to Bridged Wi-Fi

Hello all,

I've been having some problems with my wi-fi since yesterday morning and I'm getting rather frustrated.

The setup I have is an ASUS RT-N66U in AP Mode, bridged to a Thomson TWG870ug, which is in bridge mode, and supplied by my cable provider, UPC Cablecom.

The Thomson router has always been pretty awful so we decided to get the N66U to extend the wi-fi range, which has worked well since last year. Unfortunately, the other day, I started having problems with the internet (which I believe was my supplier's problem and not one on my end) and so I powered off the routers and powered them on again. That's where the wireless problems started.

My various devices could connect but there was absolutely no internet connection. So, after a day, I decided to just reset both routers. I set them up in bridge mode (I think I did exactly what I did during the initial set up months ago) and all seemed fixed. The internet connection was fine on both my desktop PC and my partner's Macbook. However, my iPhone refuses to connect to it. It just remains stuck on the connecting stage. The televisions I had connected to the wireless also cannot connect. My laptop can connect but it is 'limited'. I've had a look at the settings on both routers but I really don't know much about what they should look like so I've come to you looking for help.

Any suggestions would be welcome.

Thanks in advance!

Update: So, I've figured out that the router is only letting, what seems to be, a maximum of three devices connect to it at a time. I turned off both routers and turned them back on again, and this time my phone, my laptop and my desktop PC connected, but when I opened up the Macbook, it can't connect now. I hope that information helps someone figure this out. I'm at a loss.

Update 2: So, after rectifying my idiotic mistake of putting the Thomson in bridge mode, all the devices, bar one television, are connecting perfectly. However, my desktop PC is now having problems. It is connected to the network but nothing is loading via the internet. I'd had similar problems with it before because it is two rooms away from the router and the Thomson's range was awful. Whenever the signal dropped from five bars to four bars, the internet would cut out. However, when I added the n66u as an access point and improved the wireless card, I had no more problems. Except for now.

Update 3: Okay, panic over, I've managed to fix all the issues. The television connection issue I resolved by manually entering the network details and the desktop problem seems to have been fixed with a simple reboot. Thanks to all those who replied and set me on the right track!

If you are running everything in bridge mode then you are getting the IP addresses directly from the ISP. Most ISP will not give you more than a single IP address. That is the whole purpose of a home router to allow you to share a single IP address.

So if you have everything in bridge mode none of your equipment even cares about IP addresses. It is not YOUR router doing anything related to giving out IP. Any restrictions are outside of your control. Your only option is to run some device as a router in your house so you can share the ip you get.

Only letting you connect 3 devices is pretty disappointing, considering that it's a new router.

I would get an exchange of the router from whatever store you bought it from (hopefully accepts returns).

Good luck! :)

Oh, I think I might have given the wrong impression. It's not a new router. I got it late last year and it's worked perfectly fine up till now. I could connect all my devices to it previously. This problem is a new one. I've updated my post to clarify that. :)

So, it's because I messed up with setting up the N66U then? I'm pretty sure I did the same thing last time (i.e., set up the modem/router from my provider in bridge mode and hooked up the N66U to it) but that was quite a while ago and I don't remember exactly.

And if that's the case, wouldn't I have problems connecting the three devices I'm able to connect to it?

 
It depends on the ISP some allow you to have more than one ip. This is especially true if they are giving you private ip addresses rather than routable IP.

It is impossible to even guess how you got this to work. Your design is completely different than your average home user install. Almost everyone has a device acting as a router in their house. Are you sure you did not run the n66u in router mode before.

Something, either the Asus or the Thompson should be a router. If the Thompson is in bridge mode it is acting like a modem. The Asus needs to act like a router to allow your local network to be shared.

No, I'm really not sure. >.>

I think I'm going to have to go back and try setting it up again. This time I'll not use the AP mode.

Thanks for the replies - it's at least given me something new to try. :)

Updated to add: Okay, so after trying to remember what the heck I had done the first time around when setting the routers up, I'm fairly certain I didn't have to do much with the n66u. Basically, it was the click of a button. So I'm pretty sure I had it running in AP mode, which would mean the Thomson wasn't in bridge mode and the n66u was just extending the range of the wireless. I hope I'm not completely wrong there. That said, I seem to be having the same problem after taking the Thomson off of bridge mode and back to router mode. Although, more devices seem to be able to connect. But not all of them, such as the televisions.
