Hi Folks, I'm having recurring internet connectivity issues with my WRT54GC. I've been through several rounds of support with Linksys regarding this issue. I have NEVER had an internet connection issue in the 5 years I've been with my ISP, nor with any of my PC's connected to my ISP, until I hooked my new WRT54GC up 9 days ago. I'm an IT professional so this has been quite frustrating as Linksys's solutions have had me reconfiguring my home network several times and waiting 24 hours each time to see if their solution has worked... and there are only so many 24 hr periods left, until I can't return the WRT54GC. Any help, comments or wild guesses would be GREATLY appreciated. I've poured through the linksysinfo.org forums and found that some people have had similar issues with their own router and internet connectivity, but nothing that matched my issue with the WRT54GC. Network Setup: Terayon high speed cable modem: ISP - Shaw Canada using DHCP dynamic IP address assignment. DHCP lease time is supposed to be 4 hrs, but I usually have the same IP address for 2 to 3 months at a time. - The Modem is not the issue, it has performed flawlessly for 5+ years. 2 PC's: One Laptop (wireless, WPA TKIP), one Workstation (wired to Ethernet port 1). Both Win XP Pro SP2, both set to automatically detect network settings. Both running Firewalls and Antivirus protection. - My PC's are not the issue, they too have performed flawlessly over the years. WRT54GC: Nothing out of the ordinary here. I've upgraded the firmware to 1.02.8 as per Linksys Supports suggestion. I've assigned a "static" IP address to my Workstation (192.168.1.100), and limited the number of IP addresses that the router's DHCP can hand out to 2 IP's. I've also set the DHCP Lease Time to 3420 hrs, or 3 days, the maximum allowed. The wireless is set to WPA TKIP encryption/security. - There might be something I'm not remembering, but Linksys Support had me unplug the WRT54GC from my home network for 24 hrs to see if it was my ISP that was causing the issue... It isn't my ISP... Possible Causes: 1. The CAT-5 Cable going between the Cable modem and the WRT54GC was too short. It was ~2m (~6ft) which should have been long enough. I had been using that cable for the past 4 years, so that doesn't seem like a probable cause. 2. My ISP is resetting my IP address every 24 hrs. Which is causing the WRT54GC to "forget" that it has a connection to the internet that it can share. My IP Address hasn't changed in the past 10+ days, so this doesn't seem like a realistic cause. 3. The fact that I actually shut-down my PC's each night, could some how cause the issue. Shouldn't be the cause as the workstation has been assigned a static IP address by the WRT54GC (192.168.1.100), and there is only one other IP address that is allowed to be assigned dynamically, to my wireless laptop. 4. Evil Nano-Gremlins have infected my WRT54GC Router and I'm in for a rough ride... Not likely, but I did feed my Mogwai after midnight the other night... The Only Solution that Works The only solution that allows my PC's to regain access to the internet while the WRT54GC is connected to my home network is to access the WRT54GC Admin webpage (192.168.1.1) and do an IP Release and an IP Renew. This needs to be repeated as needed usually once every 24 hours (I'm only around my PC's ~8 hours of the day mind you). Once the IP Release/Renew has completed both PC's regain their internet access, until the next internet disconnect... Point of interest while the internet connectivity issue is present: 1. The IP addresses of both PC's never change, even after the IP Release/Renew. 2. The WRT54GC Admin Webpage is ALWAYS accessible by both PC's while the internet connectivity issue is occuring. 3. According to the DHCP Client Table the lease time for the IP's assigned to the PC's has still not expired, although the time is decreasing as it should be (lease time is set to 3 days, 3420 hours). 4. The IP Address assigned to the WRT54GC by my ISP has not changed. If anyone has any ideas, what might be going on with my WRT5GC, please post any comments you might have. I really feel like Linksys has dropped the ball on this issue and to date all my networking gear for the past 6+ has been Linksys, so I do have some faith in their hardware, just not the WRT54GC that I purchased.
