Airport Extreme

22 posts in this topic

Posted

I just went out and bought the new AirPort Extreme. I set it up with AirPort Utility, and it broadcasts my network but in AirPort Utility it shows there's no internet.

 

Now, the thing I don't understand is when it's plugged in via the modem it doesn't show the internet. But, if I plug in Comcast modem into my old Netgear G Modem, and then plug my AirPort Extreme into that, it shows there's internet in AirPort Utility.

 

How can I get it so where I can disconnect my G Modem completely and run my Comcast modem to the AirPort Extreme?

Comcast wanted $49.95 to diagnose and fix the issue, I told them "######" and they hung up on me.

Do you want to use the APE as your gateway or as just an AP?

Normally on a cable modem when you swap out the device connected to it, you have to power cycle the modem because of new MAC address.

If your wanting to replace some router with the AirPortExtreme then you most likely need to power cycle the modem.. What modem do you have? I have the SB6120.

I would suggest your remove power from the modem, wait 30 second then plug it back in and after it has powered on and you see sync connect your APE and power it on.. Then you should be good.

maybe your comcast router is doing something like IP addresses in the 192.168.x.x range and the Airport is broadcasting in the 10.0.1.x range by default 

 

so the DNS server the airport is looking for isn't matching or something 

 

is the airport in bridge mode? does the comcast modem even have DHCP

I'll have to do that, I thought it said just turn the modem on and off again. I have a Ubee U10C018 modem.

It was in Bridge Mode, but I read somewhere on MacRumors to put it on DHCP and NAS. That gave me internet for about 3 minutes. I have no clue what Comcast modem I have. It's a Ubee U10C018 modem.

Didn't you say you updated to 50mbps? Somewhere

This modem

http://www.ubeeinteractive.com/products/cable/u10c018

Is only docsis 2, you sure your getting 50mbps?? Are you in the EU? That maxes out at 50, but your limited to 1 channel.

Why would you put your APE in bridge mode?? No that is not what you want. You will want DHCP and NAT, not sure where you read NAS??

Dude that U10C018 is OLD, Really Really OLD!! Like 2004 OLD!! Your not going to see 50Mbps with that if your in the states that is for sure.

Yeah I'm paying for 50mb/s. When I out it in DHCP and NAT it worked for alittle bit, and then stopped. Should I go and buy my own modem and save $7/mo or ask Comcast for a newer one.

I bought my own quite some time ago - already made back the cost.. So lets see, look in the old email vault

sku: 210809636

description: Motorola SURFboard 6120 DOCSIS Cable Modem - 1 x F-type , 1 x RJ-45 10/100/1000Base-T LAN - 222.464Mbps - External

qty: 1

ship date: 8/25/2009

Aug 2009 = 4+3x12+11 = 51 months x 7$ your at 357$, minus my cost at 79$... You do the math ;)

Mine is still going strong, I see no reason to change it out. Its docsis 3 does 4 channels down x 4 up - I only see 3 up though with comcast

, .. Now the new stuff is more channels. If died tmrw I would be ok with it, and just buy a newer 8x4 one ;) Prob go with this one

http://www.amazon.com/Linksys-DOCSIS-Cable-Modem-DPC3008-CC/dp/B006IJHK96

its on their approved list.

Yeah I've been looking at buying my own. My question is, if I buy this, will this let Airport Extreme see the internet? I can see the AirPort Extreme, but no internet when it's just those 2 hooked up. But if I have the modem hooked to my old router, and my old router hooked up to my AirPort Extreme, then I see internet.

That sounds like a mac problem, does your old router clone a mac?

You clearly removed power from your modem, then let it resync back up, etc. Then connect your APE and turned it on so it could get IP via dhcp. You need to be in dhcp+NAT mode, your going to get your IP address on its wan via dhcp, and you want it to do nat so you have multiple devices behind it.

Be it new modem gets your APE on the internet is really besides the point, your old modem is not capable of doing the bandwidth package your paying for ;) There is no possible way to get 50mbps down from an old docsis modem with only 1 download channel ;)

So you need to replace that if you want to see anywhere close to what your paying for ;)

So what mac does your old router have on its wan? You could clone that on your APE.. Hmm quick google shows that apple does not support this feature?? You could contact the ISP and ask them if they have your modem locked to specific MAC because your router does not suppose cloning.. Its just freaking amazing of apple not to support such a basic function of a nat router it is high end router.. Really?? They sure like to cater to users that would just be too stupid to know what mac cloning is would be my bet ;)

Only reason is I can go get it from BestBuy tomorrow before work.

Yeah that one is on list as well, but its only 4x4 not 8x4.. I would go with 8x4, but yeah that one is more than capable of doing 50mpbs. If you can not wait, then sure stop by and pick it up.

What do the channels do?

Docsis 3 allows for channel bonding, this can handle congestion better. And also allow for much higher top end speed, but the big thing is the use of multiple channels that are bounded together

I believe you can look on your modem at 192.168.100.1 as well for your signal info, notice the 4 channels here in downstream and 3 used for up.

post-14624-0-61111200-1385421388.png

If you have 8 channels vs 4, its highly unlikely that all 8 out of those get maxed out, etc. And your more likely to be able to get your rated speeds without any issues even in prime time, etc.

Not that you can not easy get your speed with 4, its just 8 gives you less likely hood of running into say primetime issues where you only say 30mbps vs your rated 50 is all.

It may or many not be an issue for you.. But It think it is like a $10 for the 8x4 one vs the sb6121 that is only 4x4.

Thank you, I'm going to pick up the 8x4 tomorrow. Comcast told me when I get it, just install and call / talk to them on the web to get it activated.

Great, so they have the 8x4 in stock near you as well.. Let me know how it turns out.

Went out and got the Motorola SURFboard eXtreme (SB6141), it's still hooked up to my G router, because this damn AirPort Extreme is being a pain the ass. I click the status which has 2 issues I guess.

 

1: Setup over WAN Found out I can leave this unchecked

2: Double NA

 

So, I have no clue what's going on there. But I did a speedtest, and it does feel faster. And if I'm being told G routers are old, I can't wait to see what the APE can do.

But back to the APE, I even updated the firmware to 7.7.2 and still having issues.

Well that is not 50Mbps -- so you got the 6141, that is 8x4 - nice.

Dude I thought the Apple stuff just works? ;) No you would not be configuring it off your wan.. You should just plug in its wan to your cable modem, and you should be done from a NAT internet connection sort of thing.

Then all you should have to do is setup your wireless security.. It should take all of like 3 minutes tops really! Maybe its defective? But an old G is highly unlikely to be able to route 50 wan to lan, I am actually kind of surprised your seeing 30+ What is the make and model of your current router?

Weird. I went to Network Preferences and my ethernet settings were set on Manually, switched it to DHCP and it finally connected.

Yeah only paying for the Blast package.

 

What's the difference between router IP address and LAN IP Address? I got a notification when I woke up on my iMac about another device using the same IP, I open AirPort Utility and it was the LAN IP Address.

 

I haven't noticed anything different from my other devices with the WiFi. I know my Xbox One still only gets 2 bars and my TV that it's hooked up to get full bars.

 

What I do like is that I can see what devices are hooked up to my network from just opening up AirPort Utility.

Well the router would have 2 addresses -- its wan or public IP.. Something other than 10.x.x.x, 192.168.x.x or 172.16-31.x.x those are rfc1918 address and are not viable on the public internet and are reserved for local use.

So your router would also have 1 of those on its LAN side, say 192.168.1.1 that would be your gateway to get off the network and use the internet. So your machines would be say 192.168.1.2-254 range

I don't know what the Apple stuff defaults too for lan addresses or dhcp scope.

What mode are you running your APE wifi in G only, N only G+N is it dual 2.4 and 5, are you connecting to which one.

As to bars -- so your saying your TV shows full bars, and the xbox one that is I assume right next to it only shows 2?

Bars don't always mean that much - what kind of speeds does it get? You sure your not connected to the wireless across the street with 2 bars.. I have seen it quite a few times to be honest.

User: How come I come I can not see my printer anymore?

Admin: Because your connected to the linksys SSID across the street! Not your linksys - Why did you not change your freaking SSID and setup security?

User: What is an SSID?

Lol, sorry for all these questions.

 

Alright, I don't know what my devices are connecting to. I have 2 networks, one is 2.4ghz and the other is 5ghz. My Xbox One was connected to the 2.4GHz and was getting like 38MB/s, connected it to 5GHz and got 65MB/s.

 

I guess everything is good to go now. Thank you once again for all the help.
