Pocket PC Forum / End Users / Pocket PC / July 2008iPAQ 4350 not resolving names with DNS
My wife has a legacy iPAQ 4350 running Windows for Pocket PC 2003. Its networking card seemed to be working normally and DNS resolution was working until yesterday. Yesterday morning I changed my router arrangement to accommodate a machine running N protocol WiFi encryption. Basically I added a second router configured as a passive switch (with its own WEP-encrypted wireless network) and reset my main router as a separate WPA2 encrypted network. This all works fine. My single N-protocol machine is happy on its network and my Pocket PC as well as a legacy laptop are happy on the WEP network. My wife's legacy iPAQ 4350, however, doesn't seem to be connecting to DNS. I've double checked several times and the iPAQ wireless card DNS IP is definitely set to the same IP as the other WEP-network devices, namely the IP of the WEP-network router (both routers being configured for DNS pass-through). I have tried removing the battery from the iPAQ and running the “welcome" utility to reset things but no luck. The iPAQ absolutely refuses to connect to any website. IE keeps complaining that “The page you are looking for cannot be found.” I have actually seen this behavior in the past with the iPAQ in question but have usually been able to make it go away by removing the battery and running the “welcome” utility. No such luck this time though! Does anyone have any idea how to fix this problem? Thanks in advance for any help!

PS—VPN does connect on the iPAQ, however, so I know I have a working WiFi connectionon it. Suggest downloading and running vxUtil and vxIPConfig from http://cam.com These will show the dns ip address if one exists and allow you to ping it and determine if it is responding. Tip on vxUtil... there are entries for all possible connection options, so you will need to spot the currently active connection...

When I ping with them both vxUtil and Z2PocketLan show reply packets from the IP address for the “passive switch” router on which I am running the 811g wireless network. Both routers are set to allow DNS relay and three other machines including one Pocket PC (Windows Mobile 5 though) are working just fine with the saying 811g wireless network. For some reason, however, on the Windows Mobile 2003 Pocket PC, DNS lookup fails. All four machines are configured identically in that the DNS address for the adapter cards is set to the IP address of the “passive switch” router on which the 811.G wireless network is running. I am completely a loss to explain why this is happening! using vxUtil's ping, what happens when you ping a "verbose" address such as "yahoo.com" ? Next clue, when you ping "yahoo.com" with a working pc, jot down the ip address from that ping, and report what happens when you use vxUtil to ping yahoo's ip address.

[quoted text clipped - 4 lines] > > Beverly Howard [MS MVP-Mobile Devices] First, thanks again! I get packets back with no problem. Of course, if I try "Get HTML" for http://www.yahoo.com I get a "Could not get IP address" error. This is definitely a DNS lookup problem but I just don't see what's going on. rather than "get html, simply enter "yahoo.com" in the ping address field... I expect a timeout, but want to confirm. My focus would be back on the dhcp... first, would confirm that ip address is really on automatic and the base ip address that the unit has really come from the router. Next, copy the dns address that the router itself shows and ping that directly... there's always the possibility that the pc's have gotten fixed or alternate dns entries. Open the router utility on a pc and confirm that the ppc shows up as an attached device and make sure it's mac is not in the router's fixed ip table. for our edification, copy the entire ip info page while connected and post that here (edit out anything sensitive) look for something subtle... like an alternate device with almost the same settings or an address with an "0" rather than a "1" Finally, you can resolve this using a fixed ip address approach by entering a high base ip and then going directly to your desired dns server.

The address is 192.168.0.104 which is within the main router's (a second router is configured as a passive switch) ip number pool. > Next, copy the dns address that the router itself shows and ping that > directly... there's always the possibility that the pc's have gotten > fixed or alternate dns entries. The router that I am using as a passive switch to connect to 11g machines does not display the IP number, only connect time, Mac address, and mode. It is clear, however, from connect time and Mac address that the router in question is “passing through” an IP assignment to my wife's Pocket PC. Furthermore, I can ping that Pocket PC from other machines on the network at that IP number (192.168.0.104). The “main” router, the one that is actually assigning DHCP addresses, does report my wife's Pocket PC name and Mac address at 192.168.0.104. > Open the router utility on a pc and confirm that the ppc shows up as an > attached device and make sure it's mac is not in the router's fixed ip > table. There is only one reserved fixed address on the “underlying” router (the one actually assigning DHCP addresses). That is the address used by my main work machine for which I require a fixed address. I have verified this visually by checking directly in the DHCP reservations list on the underlying router. > for our edification, copy the entire ip info page while connected and > post that here (edit out anything sensitive) look for something > subtle... like an alternate device with almost the same settings or an > address with an "0" rather than a "1" Time : Thursday, July 01, 2004 6:01:50 PM Firmware Version : 1.09, 2006/10/23 WAN Connection Type : PPPoE Cable Status : Connected Network Status : Established Connection Up Time : 4 day(s), 16:17:17 MAC Address : 00:17:9A:48:43:90 Authentication & Security : PAP IP Address : 74.xx.xx.xxx Subnet Mask : 255.255.255.255 Default Gateway : xx.xxx.xxx.xx Primary DNS Server : 204.101.251.1 Secondary DNS Server : 204.101.251.2 BigPond Server Name : BigPond Status : Unknown (Please wait...)

First, I have been wondering how this legacy Pocket PC got remained WINDOWSMOBILE6 since that is not the name that we assigned to it. Second, I have no idea where the second entry, that is, the WINDOWSMOBILE67 entry came from—furthermore, the Mac number doesn't correspond to anything I know of. I wonder if I should simply try renaming the Pocket PC to its original name before I try assigning a fixed IP number you suggest in the next paragraph. What do you think? Again thanks so much for sticking with this! Very much appreciated indeed! > Finally, you can resolve this using a fixed ip address approach by > entering a high base ip and then going directly to your desired dns server. Probably not, if I understand you correctly here. The reason for adding the second (“passive switch” router) was that I needed to operate one wireless machine on 11n yet be able to continue to operate several legacy machines on 11g. That meant I was stuck with having one router providing WPA encryption and another providing WEP. > Beverly Howard [MS MVP-Mobile Devices] On Jul 28, 9:46 am, "no_spam_paque...@uwo.ca" <paque...@uwo.ca> wrote: > On Jul 25, 8:19 pm, "Beverly Howard [Ms-MVP/MobileDev]" > [quoted text clipped - 113 lines] > > > Beverly Howard [MS MVP-Mobile Devices] PS--Tried fixed address--no luck on that either!

If your ppc is named differently than the router table shows, that's also a red flag.

I believe that to be the case. The only device configured for pppoe is the main router. > If your ppc is named differently than the router table shows, that's > also a red flag. Actually, I changed the name back to the former name but it got changed back to yet another name (in the main router wireless table)-- this time WindowsMobile97 right after doing an ActiveSync sync session. Thanks for all the help--I'll post here if I ever get to the bottom of this. > Beverly Howard [MS MVP-Mobile Devices] On Jul 28, 6:48 pm, "Beverly Howard [Ms-MVP/MobileDev]" <BevNoSpamBevHoward.com> wrote: > essentially, I'm lost... > > the only remaining observation I have is the pppoe entry... if either > the main or "passthrough" assumes the ppc has a pppoe client, No--not as far as I can tell! that would > stop things cold... for any ppc setup, the router should be the only > pppoe login to the service and providing non pppoe connections to > everything behind it.

I've already had to replace the motherboard once on the iPAQ 4350 in question because of WiFi failure and I see that loads of other people have had problems with the WiFi circuitry on that particular board (the WiFi board seems to last only about two years). It was starting to become erratic long before I added the second router. The “smoking gun” appeared early this morning while I was experimenting with 64-bit instead of 128-bit encryption to see if that would make any difference. During that process DNS lookup worked once, but only once so I think I'm dealing with a failed WiFi board again. Thanks again for your help!

Glad you are headed toward resolution. fyi, are you aware that a number of your posts are being posted multiple times? Since you are posting via google groups, is there a chance that you are reposting my multiple clicks on their send button? Thanks, Beverly Howard [MS MVP-Mobile Devices] |
