Question: Is it possible to attach (daisy-chain) a Linksys WRT54GL to this in order to have more ports?
Document: I bought the Cisco-Linksys E3000 High-Performance Wireless-N Router to try to improve the wireless connection from our cable modem in an upstairs office to a Roku on the ground floor in order to stream live HD video (MLBTV). The speed of the E3000 may have been faster than the old wireless router (a Lynksys WRT54GL 802.11g), but the signal was much weaker on the 2.4MHz band (3 out of five bars) and especially the 5MHz band (2 out of 5 bars) of the E3000.
In order to do that you have to access the router's admin page (1) turn off the DHCP server (2) change the router's IP address to something other than 192.168.1.1 (which is the default primary router IP address) (3) turn off any port forwarding that you might be using for game boxes. (5) the ethernet from the primary router needs to be plugged into one of the "switch ports" NOT what would normally be the input from the cable modem. So you effectively lose one port but you have a 3 port switch with a wireless access point that operates in G mode.
I attempted to boost the signal using a tinfoil Windsurfer Antenna, but it made the signal even worse. I reinstalled the very reliable $60 Lynksys WRT54GL (5 out of 5 bars), and I returned the Cisco-Linksys E3000 High-Performance Wireless-N Router. I will next try to improve the connection by avoiding wireless with a NETGEAR XAVB101 Powerline AV Ethernet Adapter Kit, but I suspect that our original wireless router may provide the best connection after all.
Just bought this, happy with its performance so far, do not feel much difference in terms of speed though, signal strength is definite stronger, covers my dead room now, much better than my previous linksys wireless G rounter.My serious complains are the setup procedures, NOT "user friendly" at all:I want to provide this feedback here as soon as possible so that you do not have the headache like I had for a few hours: (this problem is common with all vendors wifi routers, I think.
For the past six months or so I have been using a Linksys WRT54G2 router for my wireless home network which only included a wireless printer. This product was unacceptable since it would randomly drop the internet connection to my WIRED computer and wireless printer. Working with various types of Linksys technical support was not successful and they finally agreed to replace the unit.In the meantime, I decided to upgrade the router to an N type since I now wanted to stream video from my internet connection to my HD TV which is on the other side of the house and a wired or powerline connection was not possible.
Not only was the interface extremely slow with every change I would make,  this piece of junk actually would drop wireless about 5 times in a single hour and a half movie. This drove us absolutely crazy. So I was off again to find a replacement and send this thing back as quickly as possible.So, what I found was that the best option for me was the Linksys E3000. This guy has the same dual channel wireless, as well as the UPnP server for hosting video and music over USB. Plus, one of the coolest things, and something that I am very happy about, is that I can go right back to my old faithful DD-WRT firmware if I would like since it is supported for this model.
Linksys E3000 had some problems, but not too bad. The overheating problem was present. But I put the unit on top of one of those laptop coolers and it worked great with no more problems. E-3000 looks great and has quite a few ports for other internet connectsions
Had the router now for about a month. Set up was quite easy with the enclosed CD. If you want a manual just go to the Cisco website [...] and download it. The wired ports are Gigabit, it has a USB port (haven't tried it out) and it's dual band.I was leery because at under $100 it is a great deal, and some reviewers had problems always having to reset it. Which was why I replaced the old Linksys router I had for almost 10 years.
After a less than stellar experience with a D-Link wireless N router that gave me nothing but connection problems and forced me to disconnect it in order to use my Xbox, I bought the E3000 and have been extremely happy with the purchase. I utilize both g and n wireless networks, and my Xbox worked without any issues while connected. My past experience with Linksys has been positive, I should have stayed with them instead of trying a different brand.
It has an extremely large coverage so if you have a large home there are no worries with TRIPLE the number of internal antennas over the other Linksys E1000 for best coverage. Plus it has the USB port for centralized file sharing with built-in UPnP AV media server. Also the Gigabit Ethernet (10/100/1000 Mbps) ports for faster file sharing with other Gigabit devices. It is the Best for: Optimized performance for smoother media streaming in "everything" that you do.
Answer: Hi Itsawrap. Yes, you can. Here's how you can do it: http://www.linksys.com/us/support-article?articleNum=132275 However, we also agree to what the other user said.
