Net access via wireless PC - possible?

I have a Power PC Mac Mini (as well as an eMac) that I'll be taking on an extended holiday with me. I also have a laptop pc with a wi-fi card, whereas my mac mini has no wireless capablility. Now, my question is, is it possible connect to the net on my Mini by using the wi-fi capabilities of the laptop PC, with my mac mini networked via an ethernet cable to the laptop? I was under the impression that you can 'piggy back' this way, but I could use some confirmation.
Thanks in advance

Hi Simon,
yes, it is possible to do this. First, you have to configure your PC to access the internet wirelessly. Then you have to enable internet sharing and DHCP on your PC. Last, connect your Mac via ethernet, open System Preferences > Network, select "Built-In-Ethernet" and set it to use DHCP.

E4200v2: Local Management Access via Wireless *ALWAYS* Enabled

I just found a slightly unsettling bug in the E4200v2 (running the latest firmware 2.0.36 build 126507).
Administration > Local Management Access > Access via Wireless ... set to DISABLED.
HOWEVER, when I attempted to access the web interface on a handy iPAD I had absolutely no problem getting through to the web interface (after providing username and passsword).
Limiting access to wired clients seems like a simple a prudent measure ... which is why this option is there for the paranoid among us.
This seems like a black-and-white bug. Comments welcome. Fix in the next firmware revisio even more welcome.

It was mentioned in another thread that disabling wireless management does indeed disable http access over port 80. However, if you're using https access--which uses port 443, that access is not blocked. So for anyone who wants to disable wireless management access, you need to enable management access via http only, and then disable the wireless access. That combination will indeed work.
I have confirmed this on my own router and can now only manage via wired connections over http.
Strange bug/oversight!

Not able to get internet access via wireless

When connected via hardwired or sprint pcs card and am able to access internet with not issues. When connected via airport I cannot. When checking the settings of airport everything looks correct (ip, router, netmask, etc.). Went to Apple store they played with the laptop and it started working, they made no changes they said. Got home with laptop and again no internet. My Windows based laptops/pc are able to use the same wireless access point and access the internet with out issue.
Is there away to reset airport? or some mac tools to help identify the issue?

They're not guaranteed to solve the problem, but they'll only take you a minute or so to try.

Conneced to wireless router but no internet access via wireless

I don't recall the physical connections being directly attached to the router. The router in question is a Linksys WRT54G/GL/GS. My initial thought was since we rolled out Voip fairly recently one of our phones might have ganked the IP address, but that is not the case. Each of them have their own IP addresses and I don't see any conflicts. I am also able to ping the router and log into it remotely from my office, which is in a different city. Could it possibly be a firmware issue?

Hi Everyone,
One of my offices' routers is broadcasting but has no internet access. The office does have internet if you hardwire in but outside of that nothing has worked so far in regards to the WiFi. I have power cycled the router and modem to no avail and DHCP is enabled but no one can get online via WiFi. It seemed to just up and decide one morning that it was not going to allow internet access.

Mx880 connected to LAN. Cannot access via wireless. ???

I have an end user on campus who has a Canon MX880 multi-function printer/copier/scanner, etc. I have it configured to a specific IP address, and connected to the college LAN via data cable, data drop. The drop is good, I have tested with a laptop. I manually set the IP4 settings on the MX880, and can ping the printer when connected via ethernet to LAN. As soon as I try to get on the the college wireless LAN, I can't ping it. I took another laptop, disconnected the data cable from the printer, plugged it into the laptop, and manually config'd the laptop to the same manual IP4 settings as the printer is set to. This time, from the other laptop, I can ping connected to the printer port wirelessly or when ethernet connected. So there is nothing wrong with the campus wired or wireless network. It's only when I try and ping the MX880, via the campus wireless network, that I have a problem. Again, I have the MX880 ethernet connected to a data drop. I have the LAN settings enabled, and IP4 manually set. I can ping the printer IP address when ethernet connected from somewhere else on the network, but I can't when I'm using the campus wireless network. And again, If I use two laptops, one used in place of the printer, but set to same IP settings, I have no problem pinging the IP address via LAN or campus wireless. Any ideas???

Most public networks (like the ones on a college campus) have built in firewalls that prevent communication between devices. They're designed primarily to give a device internet access but not to let 2 devices on the network talk to each other for security purposes (so the guy in the dorm next to you can't hack your computer). Trying to use the printer with a public network probably wont work.

Time-Based Net Access by Hour

Hi,
I'm looking to enforce internet usage rules during a typing class. Is there a way to block access to Safari for only certain times under OpenDirectory and/or the Workgroup Manager? I have kids that need access at other times of the day, but during one particular period I'd like to be able to disable their net access.

It should be possible with 24 'recurring' statements.

Bridge to bridge and bridge to access-point via wireless is it possible.

here;s my topology i am trying to configure. i have a router whose ethernet is connected to a bridge.this bridge 1 is connected to a bridge 2 via wireless. now i am trying to connect a access-point via wireless to this bridge2. is it possible for bridge 2 to support connectivity to the bridge1 and the access-point both of them via wireless.
can someone pls help me on this.
waiting for someone to reply.
regards
sebastan

You can set up each radio in the access point for different functionality. Considering the scenario, this can be done by setting up the SSID for the G radio and another SSID for the A radio. Then, set the role in the radio network parameter for the G radio to access point and for the A radio to the root bridge role.
ou can prevent unauthorized users from reconfiguring your access point/bridge and viewing configuration information. Typically, you want network administrators to have access to the access point/bridge while you restrict access to users who connect through a terminal or workstation from within the local network.
To prevent unauthorized access to your access point/bridge, you should configure one of these security features:
Username and password pairs, which are locally stored on the access point/bridge. These pairs authenticate each user before that user can access the access point/bridge. You can also assign a specific privilege level (read only or read/write) to each username and password pair.

Web-UI error message "Access via 'NULL' object reference not possible"

I need some help, I'm not a Basis person but I need to get this connection problem resolve.
This problem is in our DEV ICWeb system. After logging in to Web-UI, I got a error message "Access via 'NULL' object reference not possible". We have 3 clients (100, 220, & 310) in DEV and all 3 clients are giving me the same error message.

Thanks Rama,
Acutally i accidentally commented the lo_nd_student = wd_context ....etc
this line was commented .
i have one small requirement to fetch data from local customised table and fill the same to internal table and bind that to table node.
my table node is student having attributes as name , city and number , all are of type strings.
now i created one custom table zstudent having ID - char of length 10,
name of type string
city of type string
num of type string
i have inserted records
but when i use select query to fill data from this zstudent to my internal table of type lt_student type wd_this->elements_student ,
im getting same above error.

hi ,
The attribute M_HANDLER is an attirbute of component controller (as told by your post) and so you cannot access it as you have done it.
You will have to access it as .
WD_COMP_CONTROLLER->M_HANDLER->GET_RANGE_TABLE_OF_SEL_FIELD(I_ID = 'S_CARR_ID' ).
Try doing it.
Or else , if you have created a similar attribute in your view itself , then it is "INITIAL" and hence you are getting the dump.
You will have to assign the view attribute "M_HANDLER" with the value of your component controller attribute "M_HANDLER" ,because all the initializations are done in WDDOINIT of comp controller and on component controller atribute "M_HANDLER".
Thanks,
aditya.

Is it possible to show a presentation from the original iPad via wireless on an older projector with no HDMI input?

is it possible to show a presentation from the original iPad via wireless on an older projector with no HDMI input? If so, what equipment is needed?

The ipad not support wireless projector yet.
The workaround is you are using computer that connected wirelessly [needs 2 wireless adapter] / via cable to projector and connected also to the wireless router.
You are controlling the computer via wireless connected to the router using remote desktop app like splashtop, teamviewer, logmein, vnc, etc. You must set the remote desktop port and app at the computer too as ipad app support.

IC WEBCLIENT: Access via 'NULL' object reference not possible

Hi,
Iam working in ABAP, and learning CRM ABAP on CRM5.0 IDES Demo system I was trying to create a new WebIC by copying one view from CRM_IC to ZCRM_IC bsp application. Following are the steps I following according to Cook book documentation.
1. I copied BuPaDisplayCustomer view and controller from CRM_IC to ZCRM_IC from
    BSP_WD_WORKBENCH by selecting CRM_IC and runtime profile = 'DEFAULT'.
2. Created a runtime profile from SPRO->CRM->IC Webclient->Customer specific modifications->Define
   runtime profile.
3. Copied the 'DEFAULT' runtime profile to my new profile 'Z_COOKBOOK'. Assign 'ZCRM_IC' by
   clicking on 'Controller and substitues'.
   BSP       Replaced Controller         BSP                 ReplacmentController
   CRM_IC BuPaMoreContactView    Z_CRM_IC         BuPaMoreContactView
4. Define IC Webclient profile:
    SPRO->CRM->IC Webclient->Define IC Webclient profile->Copy the DEFAULT profile and assign it to
    'Z_COOKBOOK',
5. Assigned the Webclient profile to the user from t-code 'PPOMW'. Selected 'USER' from the
    existing 'Position' and Goto->Detail object->Enhanced obj descrption.Selected IC webclient from the
   list and created Infotype assigned Webclient profile 'Z_COOKBOOK'.
6. Execute the ZCRM_IC from SE80 by rightclick and Test. Here is my problem,Iam receiving the
   following error in the webpage.
     The following error text was processed in the system CR7 :
           Access via 'NULL' object reference not possible.

I check the CRM services and all are active, using IE8 web browser. I just copied the view and controller
from CRM_IC into Custom BSP application i.e., ZCRM_IC.
Above error is occuring even If i run the standard CRM_IC BSP application and select one simple view.
from SE80.
Not sure whether any additional configuration or any special roles to be assigned to the Webclient profile.
Thanks,

Hello
The most important information is (again) missing: which object reference is initial ("NULL")?
The ABAP dump will tell you.
Below I show an example how this can happen (and be avoided):
LOOP AT lt_accountings INTO ls_accounting.
lo_po_account ?= ls_accounting-accounting.
ENDLOOP.
" QUESTION: Are you sure that lo_po_account hold an instance ???
" If LO_PO_ACCOUNT is empty the following statement will give you the dump.
ls_mepoaccounting = lo_po_account->get_data( ).
" And that is how to avoid this (at least the dump. Whether your logic is still ok is another matter...)
CHECK ( lo_po_account IS BOUND ).
ls_mepoaccounting = lo_po_account->get_data( ).
Regards
Uwe
