Router gives wrong IP to Wireless stuff

[FatRakoon]

This is one that has bugged the heck out of me for a few weeks now.

The router is an ASUS N55

The devices that are connected to the router through Ethernet, all connect just fine, and are given their IPs as normal.

However...

Quite often, when I connect via Wireless, they seem to be given the wrong IP?

Even weirder, is that they see the wireless network, I tell them the password, and they connect and they say everything is good, and they are seemingly given a good IP, but its wrong, and the default gateway is also wrong.

i.e

My Windows Phone

Connected etc, but its IP is 192.168.0.147
It says the gateway is 19.168.0.1

But its 1.1 NOT 0.1

So, the third number is always a ZERO instead of a 1

I have had this on everything wireless, while its never done it before?

With Laptops, I was able to manually setup the network to gedt it to connect, and with my Windows Phone ( 535 ) and my Samsung Note 3, they are both currently working as they should be, as is my wifes Samsung S3, however none of my family's phones are working on it. My youngest son has the 535 the exact same as mine, and theyt are identical in every way, but I cannot get his to work?

It started doing this about 2 weeks ago ( about ) and I am sure it must be the Router itself, but I dont know?

I am also using a Netgear Modem router as a switch, and its WIFI was indeed on 0.0 however, I have disabled the WIFI on it, and I have fully shutdown and started everything back up, just in case they were conflicting, but its not helped.

I have also done a backup of my settings for an older config, and I have also done a full factory restore and manually set the router up again, and has not helped either?

I dont really know what else to try?

Any ideas will be fantastic.

 

[FatRakoon]

Oh holy moly.

Ok, well, I am mostly sure that I have disabled DHCP.

I know the ASUS is 1.1 and the netgear is 1.100

I think that somehow the netgear went back to 0.1 perhaps?

Now, I am sure that what I did, was manually set the netgear to an IP on the same subnet... Im sure that I set it to 192.168.1.100 actually, and that since the XBOX, SKYTV and the MediaPC are all on Ethernet, and that the 4th ethernet port went straight to the homeplug, and they worked fine, and as I said EVERYTHING works fine through ethernet actually, I thought that it was all ok?

The Wireless of the Netgear WAS enabled and so I have switched that off.

It made zero difference and so just now I once again turned it all off and then back on, bt left the netgear off

Wireless is all working perfectly now.

I will try to re-enable the netger ( WITHOUT ITS WIFI ) and see how that goes?

It should be good, but shy it did this I dont know?

I have NOT checked the settings on the netgear yet. I will do that shortly when I tuirn it back on.

Thanks guys.

 

[FatRakoon]

Yes, I did manually set the IP of the netgear, as I said, to 1.100
And I did turn DHCP to OFF so the ASUS was the sole controler of the network.

I wanted the Neatgear to act as a 4 port switch and nothing more.

The annoying thing is that it did work and it worked great for a while and it was only 2 weeks ago that I started to have these issues.

Well, not started but rather they either just happened suddenly, or more likely, is that I just noticed them.

 

[FatRakoon]

Ok, well as I said, the netgear was only ever used as a switch. Its a modem and so it has no WAN port, it has its RJ45 and the 4xCAT5 ports.

As for DHCP, this is OFF.

Now, I was getting seriously confused about things, I have been switching the routers both off entirely, and starting the asus back up but not the Netgear and this has seemed to cure it.

So... I got the boys to get teh 5 port from the attic as I cannot go into the attic anymore and they have been using that since yesterday and guess what?

Its still doing it... So after all that, it has NOTHING to do with the netgear after all??

Ok, so the Homeplugs have been mentioned a couple of times now, and as it just so happens, my son said that his stopped working and he has swapped his with his sisters. She now whines and so I have given her one of the older 200MB ones.

So, I wil indeed remove the home plugs for the time being.

Does the XBOX 720 have Wireless?
My daughters PC I will just give her a USB dongle and the Media PC is here with me and so I will put the card back in, and Sky obviously has WiFi.

Lots to do then... I will update you when I know more... Which will be interesting cos Im still no better off than when I first had the issues but now Im thinking its the ASUS??

Its set up as 1.1 and it while it remembers the IP of all the devices that have connected before, when it assigns new ones now, it defaults to 0 instead of 1

Another quick solution would be just to swap the ASUS only and see how everything else goes? - I will do that first actually... It will be the easiest solution surely?

 

[FatRakoon]

Network Map - Sure.
This is an old image, but the network is the same setup.

What ISP.
Its SKY.
My router however is my own shop-bought ASUS
I have plopped the Sky router back on for a bit.

 

[FatRakoon]

Just notice some changes...

The HALLWAY WIFI REPEATER is NOT on there.
The Linksys was changed to the Netgear some time ago.

 

[FatRakoon]

The attic switch, has NOT been used for ages.
I have had an accident and I am entirely unable to go upstaris and so thats been out of the scene for a while.

The attic stuff has NOT been in play at all and has nothign to do with this.

I should do a more up to date plan of the network as-is really

Erm, the attic stitch, is now down here and is in place, instead of the NETGEAR.

The ASUS has for the moment, been replaced with the Sky router.

I am doing this, as a temporary measure. I want to know that the HomePlugs are not the issue, or rather they are not DIRECTLY the issue.

So, before I remove them from the situation, ( which will be a bit of work for me to do, AND to still have internet access for the rest of the house ), I have decided to try the easier steps first.

One of the most handy things that I have with the ASUS, is that once it assigns an IP to a device, it keeps it.

Even after I add remove, kill off, and then re-add a device, if it was 69 before, it will be 69 now... I find that extremely useful rather than other routers I have where is simply assigns the next free IP, and the devices can be aby number each time you start things back up!

Unless you're deliberately using DHCP reservations (via the MAC address) there's no guarantee that you'll get the same device IPs.

With the Powerline adapters take the simple step of using your own encryption keys. If you are cross connecting with another local Powerline network it'll fix it.

Im not deliberately doing it myslef, but the router is clearly defaulting to do this yes.

Personally, I'd be ditching all the homeplugs and running ethernet to each device. Zero power usage and 100% speed with zero downtime.

I'd also use one central switch instead of multiple small switches.

I'm not a fan of using routers in non-router mode. You can get some very odd behavior from them, especially cheaper models.


-Also, the hallway wifi repeater, what make is this? How is it configured? does it have a DHCP server?

Yes, Ethernet to each is a preferable option, but this is a simpler and easier option that has worked perfectly up until just the other week.

One Central Switch - Again, this will also then mean a load of cables coming from it, to each PC... Its just not plausible in the home.

No I agree with the use of the router as a Switch, but its simply a case of needs over money. Again, its been flawless until just recently.

The Repeater is NOT BEING USED.
It DOES however have a DHCP mode, but asI said, its not in use, and it is NOT connected either.

Personally I would be tempted to have only one home plug per room, connected to a small switch instead of multiple powerlines, and try use a dedicated cable if possible.

Another note, have you tried entering 192.168.0.1 in the browser to see if it takes to you a device web page? Or even pinging it?

Yes one homeplug per room.
My bedroom only has the Media PC running now. I have asked the missus to unplg the Apple one. Its not been used for a long time, but it has still been plugged in, so its now out.

The Boys room - Yes, this has the two in there and I may change that, but to be honest, I might just remove them entirely and put the gits on Wireless.

Entering an IP
Yes, I have tried but the page does nothing. it simply tries to connect and then gives up. There is no gateway as such on ajything but 1.1 and thats been the ASUS

What brand and model number are all of the HomePlugs? I know some of the more expensive Devolo ones can have advanced features that could possibly cause DHCP conflicts.

Hell, ok, well they are a mixed bunch. Some are 200MB and some are 500 but they are all compatible.

They are a mixture of TPLINK ( 2 different models all 200MB ) and also DLINK ( the 500MB ones )

I was in the process of upgrading them to 500 cos 500MB ones are so cheap now, but in truth, the 200mb ones are just as good... Its only when I copy a load of stuff or a massive load of data over than I could need the 500MB ones and every time I do, I just dump it/them onto a USB drive anyway, so I might just stick with teh 200MB ones cos they are all TPLINK and there will be less chance of any issues maybe?

 

[FatRakoon]

Well, completely removed all homehubs now, only have the SKY Modem on, and after completely uninstalling any and all wireless capabilities on all devices, it does seem to be working.
A days test showed me that all devices including Wireless, were given working IPs
I have fully reset the ASUS and connected that back up instead of the SKY one and after re-entering the login info, it connected back up and again, that too, is now giving all wireless devs, a normal sensible number again.

So far, is so good.

I do not know if there is anything in particular that has done this, and what I am going to do, is restore the things like the HomePlugs back on, one by one, until they either start to go silly again, or they get to all of them in, but what I will do, is take my time and give it at least a day of testing between each one, to try to make sure.

Thansk for the help everyone... Its very much appreciated, so thank you.

Oh god, I rememebr that signature.

Key areas? LOL

My wife hasnt touched my "Key areas" for months!

Anyway, you may be on to something there! I was thinking of having one on every socket, what do you think?
