Losing wireless http connection periodically but not Internet - Netgear Router WGR614v5

I have been using a Dlink DI-624 router and Dlink DSL 502T modem very succesfully to access broadband internet. During an equipment move I have damaged the power adapter to the DI 624 so have replaced it with a Netgear WGR614 v5 router.

My Dell laptop is running XP Professional up-to-date with latest patches using a WG511v2 PCMCIA network card. Both router and network card are running the latest DLink software available from DLink's Australian support site.

The other Dell laptop is running Vista (Home Edition) up-to-date with latest patches. It uses an internal wireless network interface.

The laptops are both running WPA-PSK (TKIP) encryption and run quite OK for a while. SIgnal strength is high. I set the key lifetime to maxiumum (256 minutes).

Both laptops periodically lose http internet conenction with http. But mail still works so there is some internet connectivity. If I reset my network card the internet http connectivity returns (for a while).

Both laptops are using DHCP to achieve an internet  address.

I had tried WEP but had the same problems of browsers losing connection. Both Firefox and Internet Explorer behave the same.

Losses can occur within minutes or a hour or more.

So in summary both laptops work fine but periodically lose http capability but strangely maintain email capability during http outages. Resetting the PCMCIA card restores the conenction fully.

How do I fix this annoying bug.

Well it sounds more like a networking issue since it happens to both computers.

1) gGET THE LATEST FIRMWARE FOR YOUR your router.

2) Did this happen on the previous router also ?

3) Can you see if there are any logging options on your router ?

I would also check the utilities at dslreports.com, including MTU, and broadband testing.
You need to catch this in alog.

Did you check the 3 event logs on the computers ?

I hope this helps !

1) had already done so - see my post
2) No ! Previous setup was fine. This is very new behaviour.
3) nothing interesting in the router log

will check other issues soon.

The line speed on my ADSL2+ service normally gives me 8 Mbps download for Australian sites and about ~ 1 Mbps upload. Goes pretty well.

Before I get to much further into testing - the actual problem is that http services go down but email still works. i.e. the internet is not dropping out totally. Just browser services - Explorer and Firefox.

Some errors of note from the log but note I've been playing around so not sure what they may indicate.

QoS [Adapter {79F41BEB-5AD0-45BF-8A71-ECAA7707C5F0}]:

It sounds like the router DHCP is messed up.Increase the Lease time to 31 days or more, and then it should only happen about once a week or two.

Also turn off QOS in the Network settings - TCPIP.
 
I hope this helps !

I can't see in the router settings any way of changing the lease time.

Can do the QoS.

Just got some advice from Netgear support (after waiting 2 hours on the phone) to put the modem - the DLink DSL 502T into bridge mode (as this device also acts as a router).

And let the Netgear WGR614 now do the login to the broadband service provider.

Have done so, my internet is live and active,  and am waitimg to see what happens.

Will report back .

P.S. Previous advice from DLink was to let the DSL 502T modem login and put the modem in the DI- 624 router's DMZ (which I haven't done in this new situation). Other DLink router adventures I've learned was port forwarding for Xbox and also the importance of LAN subnet masks to stop gamer dropouts. Not saying any of these bits are relevant here - just that the whole router business is quite a murky black art.

Bridge mode for the modem appears to be the solution for the router's problem. So far so good.

I'll give it another 24 hours before pronouncing it a success.

Yep - looks like bridge mode was it ! No more problems.
