Current home network consists of:
1. Cable Modem wired to Linksys EA4500 router (192.168.1.1)
2. EA4500 hard wired to Cisco Catalyst 2950 Patch Panel
3. Multiple Port LAN for 2 hard wired PC's, printers, etc.
4. Wireless PC with Linksys WPC300N
5. Wireless Laptop with Linksys WLP300N
6. Second Router Linksys WRT54G (192.168.1.2) is hard wired to Port 1 from the Patch Panel, configured as wireless access point (DHCP disabled) for "G" wireless communication distance 40 feet) a DVR (Replay TV)
7. Security for all components is WPA2/Personal
The Linksys EA4500 replaced a prior main router, a Linksys WRT300N. With the prior WRT300N router in place, the above system worked flawlessly for many years. Since the EA4500 was installed, the WAP54G will not recognize or receive the wireless communication from the secondary router WRT54G. Therefore the hard wired DVR does not receive any menu guide data.
Note that, the secondary router (WRT54G) has a separate IP 192.168.1.2, is "broadcast enabled" and may be successfully pinged in the current set up. As a temporary step, when the WAP54G is hard wired to the either a free port on the WRT54G, or directly to the patch panel, it may be successfully pinged as well. However, when the WAP54G is moved approximately 40 unobstructed feet, on the same floor in a clear sight line, it cannot be pinged wireless.
Although not life threatening, this situation is a great annoyance. If anyone has any ideas (other than the purchase of additional new hardware), I would appreciate insight as to where to look for configuration problems, et al.
Also, I wonder if the WAP54G may be able to receive strong enough "G" communication directly from the EA4500, assuming the EA4500 2.4ghz channel transmits in G mode? The overall distance seems a bit long (approximately 75-100 feet, over 3 floors, however, there is no concrete between floors or steel construction). There is also a possibility for a manual set up of the DVR network configuration, including the entry of the IP address, subnet address, default gateway and 2 separate DNS addresses. All are available, except the DNS address of the main router. How may the main router DNS be determined?
Assistance, insight and suggestions are warmly encouraged.
