Help HELP!!!: Superpad 2 / Flytouch 3 - Internet

[hannavrielink]

Hi!

I'm a total noob and need some help. We've got a Flytouch 3. Tried to configure Ethernet. Found IP-address, Gateway and DNS. It won't get a connection and our own pc keeps giving an IP conflict error. We have a router with a switch. I tried different ports on the switch but still it won't work.

PLEASE HELP!!

It sounds like your computer has a static address assigned to it of (probably) 192.168.1.2. and your router is assigning the same number to the tablet under DHCP.

To be sure we would need a lot more info -
computer operating system? how many devices do you have on your network? can you access your routers config page via http? Do you know how to change a static assigned address to DHCP? Is your routers address 192.168.1.1?

Thanks for responding, here are the answers:
Q1: Windows XP
Q2: Only 1 pc is connected and 1 mediaplayer (but that's the cable we're using for the Tablet
Q3: I don't know how to access my router config page via http
Q5: No idea how to change a static assigned address to DCHP
Q6: My IP address looks something like this --> 83.82.184.65 (that should be same as the router's right?)

N.B. I already tried via command page to change ip but that didn't work either.

Thanks, I really hope you can help me!

If your computer has an address of 83.82.184.65 then it cannot obtain an IP address from your router.
First off disconnect your tablet from the network
Connect your computer to the router via your switch
Ensure your computer is set to DHCP by..

left click the start menu (bottom left of your screen)
left click 'Control Panel'
double left click 'network connections'
double left click 'local area connection'
double left click 'Internet Protocol (TCP/IP)
ensure the 'Obtain IP Address automatically' and 'Obtain DNS server address automatically' bullets are selected
click ok & wait until the box closes

Your computer is now DHCP and should obtain an address from your router, it will most probably be 192.168.1.something, check it by...

left click start menu
select 'run'
type "cmd" in the box, without the quote marks.
A black box will open.
type "ipconfig" without the quotes
It will display your IP configuration... if it is not 192.168.1.something reply here with the info it displays.
If all is OK you can now connect your tablet and it should just work as it should already be set to DHCP.

I checked the first step, this was already configured like you said. Here's the printscreen from my command page (it's in Dutch, I hope you can read it):
"Ethernet-adapter LAN-verbinding:
Verbindingsspec. DNS-achtervoegsel:
IP-adres. . . . . . . . . . . . . : 83.82.184.64
Subnetmasker. . . . . . . . . . . : 255.255.248.0
Standaardgateway. . . . . . . . . : 83.82.184.1"

So pls tell me what the problem then is..... Thank you!

Your problem is your computer cannot obtain an IP address from a DHCP server.
The process is your computer knows it has some form of network connection when you plug the ethernet cable in. Is sends out a "hello.. I'm a computer and would like to talk to anyone TCPIP. Can I have an address that I can use please" message.. it will keep sending those requests for a set time, about 30 seconds. If nothing replies it takes an address in the simple IP protocol range... like 82.xxx.xxx.xxx in the hope that there is another computer attached to the network that has done exactly the same and given itself another IP address in the 82.84.xxx.xxx range. Your router is not a computer... it is more 'intelligent', it comes into existence with an address, that cannot be reproduced over the internet.. a special address of 192.168.1.1 or 192.168.0.1 (usually), It also usually comes into existence with a thing called a DHCP server. This is a piece of software that listens on the network ports for any "hello.. I'm a computer and would like to talk to anyone TCPIP. Can I have an address that I can use please" messages... when it hears one it consults its configuration which stipulates the range of addresses it is allowed to assign and then it picks the next one in the sequence and replies " I'm a DHCP server and I authorise you to use the address of 192.168.1.2 (for example)for the following 20002 seconds (or whatever)"
Your computer is NOT receiving this message!.
Once both your router and your computer are using the addresses in the same (subnet) range they will be able to communicate... AND NOT BEFORE.

So.. if your router has DHCP enabled and your computer has DHCP enabled and your computer cannot hear your router they will not be able to communicate. Setting your computer to a statically assigned address wont work either because it cannot hear your router for some reason.....you need to discover why that is.
If you hard reset your router it will default to DHCP on (I believe ALL routers default to DHCP on). If your computer is set in network properties to automatically obtain IP address then it will work once you have connected the via rj45, unless one or other of them are FUBAR

You need to check that you get connect lights come on adjacent to the ports that you connect the rj45 plugs in, in your computer, your switch and your router. There are usually 2 lights, one is a connect light and the other is 100Mb light..so long as each time you connect an rj45 at least 1 light comes on then the connection should be good

like 82.xxx.xxx.xxx in the hope that there is another computer attached to the network that has done exactly the same and given itself another IP address in the 82.84.xxx.xxx range.

82.x.x.x [nor 83.x.x.x in the OP] is not in one of the three Private Network subnets nor is it in any of the other Special Use address blocks so I was wondering where you got it from.

...

I dunno.....sorry everybody....big brain fart. 169.254.*.* is the autoconfig range....

so..the OP,s PC is getting its address from the router which then must have an IP of 83.82.184.1 as that is the dhcp'd gateway.

This is a corporate address and would not normally be right for a domestic residence, especially as the subnet allows for ~768 nodes. (as the subnet is 255.255.248.0 the last three bits of the third octet are allocated as node address not network address, so 83.82.184.1 is in the same network as 83.82.254.254)

So I guess the question is WTF!

Is this just a simple domestic computer - router - internet set up for your home or is it a home computer - router-vpn-vpn-router-corporate network setup?
If it is just your home internet access setup I suggest you ensure you know your ISP logon details and hard reset the router to clear the 83.82.*.* addressing. It should restart with a 192.168.0.1 or 192.168.1.1 address, then reconnect your computer, do the ipconfig thing to check the address given to it and the gateway address, point the internet browser to the gateway address, navigate to the WAN setup config page, enter your ISP connection details and then connect the tablet

How did the router come by this address? Did you buy it from a shop new or did it come from a sale of business equipment/car boot sale or maybe given to you from your workplace? - just trying to get a handle on things....If your tablet or your computer is reporting IP conflict errors you will be pi$$ing someone off on the LAN as your traffic is getting out over the internet, I suggest you disconnect whatever device brings up the conflict until this is resolved.

Got any of the potato juice left? I need to change.

which appears to be a Dutch isp.

They might be dishing out static IP addresses like some of the UK ones used to [still do in some instances].

I would guess this is actually: 83.82.184.65/30 giving the following details:

Network: 83.82.184.1.64/30
Netmask: 83.82.184.1.252
Usable Hosts: 83.82.184.1.65 ... 83.82.184.1.66
Broadcast: 83.82.184.1.67

Hopefully this will enable you to successfully assign your tablet a static address of 83.82.184.1.66 and everything will work.

One warning though, your PC [and tablet] are directly accessible from the internet and, with a Widnoz PC that is extremely undesirable.

I would suggest you ask you Dutch ISP how to configure your router for NAT and assign all your machines private addresses in one of the 192.168.x.y subnets using either DHCP or static addressing.

Got to go now,

Thanks for the rescue TB.....a good job the ISPs went over to using NAT for us poor users!

by 83.82.184.1.66 do you mean 83.82.184.1:66 ? coz you have left my pay grade with that notation!

Why does the OP's computer cause IP conflicts...is it because you are only allowed one node on the IP? If so the user would have to enable windows internet sharing on the main IP number.....eurgh!..how 90's!

Sorry, that should read 83.82.184.66.

No, because it is a CIDR/30 subnet it has two bits, four addresses. Two are [historically] reserved for the network and broadcast addresses leaving two usable addresses: .65 and .66 for his network devices - PCs or tablets in this case.

Technically speaking as CIDR declared RFC 1878 obsolete five or six years ago the reserved addresses could be used to give a total of four network devices...

Hi everyone!

Thanks for the answers. But I can't solve the problem, because I have NO idea what y'all are talking about :S We don't have a public pc or old school or company pc. It's just a Dell bought for private use. It is Dutch as one of you guessed. Pls tell me stepp by step what I have to enter on the Ethernet config on the tablet.

It asks for the following info:
- Enable Static IP
- IP address
- Gateway
- Netmask
- DNS

Also, if I have security problem how do I fix this. I cannot stress enough, please use LAYMAN terms!!

Thanks again!

That would be me then!

Assuming your router has IP 83.82.184.1.65 you should try these values:

Static IP: 83.82.184.66
Netmask: 83.82.184.252 <- Corrected Value !
Gateway: 83.82.184.1.65
DNS: Either use the same value as your PC uses or, as I do, 208.67.222.222 which is the address of one of the OpenDNS servers.

That should work but, as I say, these are public IP addresses and I could connect directly to your router, PC and tablet with ease.

To fix this serious hole you will need to reconfigure your router to enable NAT so it assigns private IP addresses to all of your network devices thereby preventing direct access from the big bad Internet. If your ISP - ziggo.nl I am guessing - supplied your router they should be able to advise on how to configure it...

If not, send me the make and model by PM, and I will see what I can do, No promises though, it can be difficult to reconfigure an unknown model unless you are sitting in front of it with the manual...

Hope this helps!

Surely TB, if this was CIDR/30 subnet then the router should have reported a subnet of 255.255.255.248 not 255.255.248.0?

This subnet has a possible 256 node addresses - not 2?
also...in the case of a 255.255.255.248 subnet, why would the two available addresses be .65 and .66? Surely they would be .252, .253, .254 and .255, with .254 reserved for broadcast and .255 reserved

Hi TB...its probably me....but that still doesn't make any sense to me.

Grab a cup'o'tea and settle into a comfy chair..this is going to be tough going

The OP stated the IP settings on his PC were
IP-adres. . . . . . . . . . . . . : 83.82.184.64
Subnetmasker. . . . . . . . . . . : 255.255.248.0
Standaardgateway. . . . . . . . . : 83.82.184.1"

I cant see how this can be right.. I think the OP made a typo.. the subnet should be 255.255.255.248....here's why.....

A subnet of 83.82.184.252 is not a valid subnet address....at least...not in the way i understand it to work, whereas a subnet of 255.255.248.0 allows for over 2000 nodes (8+3bits) on the single network that spans 83.82.184.* to 83.82.255.* network address. I would have thought the ISP would want to limit the node addresses to maximise their network addresses, so a subnet of 255.255.255.248 makes much more sense to me..that gives 8 nodes (3 bits) in each of 32 (5 bits) network addresses on 83.82.184.* alone.

With a subnet of 255.255.255.248 just the IP addresses
83.82.184.64 - 01000000
.65 - 01000001
.66 - 01000010
.67 - 01000011
.68 - 01000100
.69 - 01000101
.70 - 01000110
.71 - 01000111
are on the same network.... but this is using a subnet of 255.255.255.248 - not 255.255.248.0, which is what the OP posted as the value in his PC...


How can the routers address consist of 5 octets?

By all means OP, see if TB's advice works for you...if not then I think i would ask you to confirm the IP settings on you PC when it is working through your router and you can access the internet. and then try the same values on your tablet except increase the last figure in the IP address by one or two if one didn't work ie
IP-adres. . . . . . . . . . . . : 83.82.184.65 or 66
Subnetmasker. . . .. . . . . : 255.255.248.0 _check this value I think it's wrong
Standaardgateway. . . . . : 83.82.184.1"


If that doesn't work contact your ISP and ask what ip address you should use for a second computer on your router, and while you are in contact with them ask if NAT (Network Address Translation) can be enabled on your router to protect your network from internet intrusion, that way only your router will have an external 83.82.184.* address, which it (your router) will translate into 192.168.1.1 and then everything else on your network can be assigned in the 192.168.1.* range and be firewalled from the internet. The 192.168.0.* and 192.168.1.* are special address ranges that are never passed through any router on the internet, so your local network traffic is kept local, behind your routers firewall.

Hi TB...its probably me....but that still doesn't make any sense to me.

...

A subnet of 83.82.184.252 is not a valid subnet address....at least...not in the way i understand it to work, ...

Perhaps that is because you don't understand the way CIDR addressing works?

If you have a Linux machine simply type this command:

ipcalc 83.82.184.66/30

and all will be revealed thus:

Address:   83.82.184.66         01010011.01010010.10111000.010000 10
Netmask:   255.255.255.252 = 30 11111111.11111111.11111111.111111 00

It is both the number of zero bits in the netmask and their location that determine the network parameters: network address, broadcast address and usable IP addresses.

Prior to the introduction of CIDR addressing the smallest allocation of IP addresses was a class C address [/24 = 256 addresses] now allocations as small as /30 [4 addresses] are now possible allowing 65 times as many allocations.

I trust this ends your confusion?

Hi TB...I don't actually have a Linux box...but I can follow what you say and I understand it. It all makes perfect sense....providing the netmask is 255.255.255.252 !!
but the OP's stated netmask was 255.255.248.0 ..which gives 2048 nodes (83.82.184.66/21)
I argued that the OP may have made a mistake and the netmask should be
255.255.255.248 - which gives 8 node adressess ,of which 6 can be assigned......or even
255.255.255.252 - which gives 4, of which 2 would be assignable.....which would be much more likely in a domestic environment would it not?

What? No Linux box! I have about 13 of which seven are in constant use; I have no widnoze boxes though.

Having done a bit more research it would appear his original netmask was correct. I committed the cardinal sin of assuming his ISP would work in a similar way to my ISP whereas it now appears they don't.

His original netmask of 255.255.248.0 WAS correct after all.

I assumed he was being allocated a static IP address as a /30 CIDR subnet for his personal use whereas he was actually being allocated a dynamic IP address from [as you quite rightly say] a much larger /21 CIDR subnet.

As the OP only has a single IP address allocated to him he will need to correctly configure his router's DHCP server and NAT facility to dole out private IP addresses to his PC, tablet, printer etc if he wants to use more than a single device.

This is why I hate trying to diagnose networking problems remotely.

Put me on site with a Linux box and the router manual and I'd have had this licked in 19 minutes flat!

Not sure, I did PM him offering further assistance but I think he might have ripped all his hair out and banged his head against one too many walls by now...

yep....maybe he did the right thing and told that ISP to sling their hook and then went to a proper one!!!

Dudes, I'm girl...that first of all. That might explain a lot too I tried to configure it the way you told me too, but it still doesn't work.

So obviously as you said I need to "configure HER router's DHCP server and NAT facility to dole out private IP addresses to his PC, tablet...etc"

How do I do this??

Thanks for all the help!

Apologies, another false assumption, slapped wrist...

If you let me know the make and model of your router I might be able to talk you through it [if I can find a manual online] or, failing that, if you were to PM me the user name and password of your router I could configure it remotely using its web interface.

Do not, under any circumstances, post those details online!
