Wireless Router only works 'Wired'

Re: Wireless Router only works 'Wired'

I rolled the drivers back a few generations and now it works fine, though I now lose WPA2. No big deal, WPA and a long password is good enough. Thanks!

The thing has Lelons though, though I'm not particularly intent on pumping any money into this old thing. Also the general capacitors area is very cool so not worried at all.

Re: Wireless Router only works 'Wired'

I flashed my router's firmware (D-Link Di-624, sort of old but works) yesterday and now I'm getting this problem. Ethernet works fine, but internet on wireless drops on a regular basis - my wireless card talks to the router just fine but after about 10 minutes I get no Internet. I usually have to disconnect from the router and then reconnect, in which case it then works for another 10 minutes before Internet again gets dropped. This was not an issue before the firmware flash.

FYI it is not overheating. I've already rigged a heatsink onto the hottest chip on the router's PCB and also over a really hot voltage regulator, and I've rigged an 80mm fan over it. It runs super cool now. No blown caps either.

Really hot voltage regulator might suggest a bad walwart or bad filtering due to bad caps in router (don't quite remember what that router looked like inside). D-Link was notorious for bad power supplies back when the 624 was new (at least around here). So see if you can find another powerbrick around the house with the correct voltages and polarity and try that.

Caps blow without bloating too.

Roll back the firmware.

Re: Wireless Router only works 'Wired'

I use a Westell Modem/Router. It has a home page on the net where I can go to change its wireless settings. Right now I have the wireless side turned off and no antenni installed on it. My new pc has wireless built into it and it hasn't picked up the Westell. I don't know if this is of any help to you but its how my junk works.

i do not remember having ANY wrt54g series with hardware issues other than bad caps.and i have had 150+ go through my hands.they get caps,tomato or ddwrt,and i never hear of problems again except 2 that were hit by lightning.

Caps just wernt big enough to handle the voltage spike or good enough esr. their hardware is so basic I've never had issues with it so I always say software. Ran a city wide wifi off a bunch and never had stability issues after we went ddwrt, other than the white collars scrapping it after we had everything running smooth

I suspected it, same type of vague posts that add nothing to the conversation. That guy just will not quit.

Name one brand that is better while not being 10 times more expensive than the old venerable WRT54G series

Re: Wireless Router only works 'Wired'

Probably your first issue is that Linksys is junk...

Re: Wireless Router only works 'Wired'

Basic question, but are you sure you have your wireless security settings set correctly on the router? WEP, TKIP, etc.

As previous folks have said, wireless is less relaible than a fixed line and especially if you live in a multi-dwelling environment there will be many routers contending for the 3 channels (1, 6, 11) if you have a 2.4 GHz AP/router. Most default to channel 6 and stay there. If you have 802.11n support than some AP/Routers can use 2 channels. Also, for the co-existence aspect, the 802.11 standards define co-existence mechanisms (CSMA - Listen before talk), but not all AP vendors implement it the same way.

You should be able to play with some of the wireless settings on your AP to see if its an interference or coverage issue. (i.e. you are too far away from the access point).
1) Try changing the channel
2) Try changing the security settings (both at the router and the client)
3) Try fixing the AP transmit power (set it to maximum)
4) Disable 802.11n, and use 802.11g

...Linksys is junk...

They are the best IMO

But yeah try moving the antennas around.

Re: Wireless Router only works 'Wired'

My sister had a similar problem, all i did was tilt the antenna a bit so it was sitting in 45 degree angle and never happened after that. This is of course not a solution for everyone, just saying small things can make a huge difference.

I doubt its due to channel, wireless networks are supposed to be able to coexist quite ok, you wont get full speeds but shouldn't disconnect.

Another possibility is interference, like the Belkin HD Powerline adapters for example.

The same guy have a few videos explaining what happens when they are used.

Re: Wireless Router only works 'Wired'

Its my belief that linksys uses some crappy algorithm to decide which antenna and thus which radio has the best signal. Try powering up with only one antenna. Or go the route I and a ton of others have and dump the crap firmware for ddwrt or openwrt.

@retiredcaps 9 times out of 10 when I've dealt with this issue it was software. Installing ddwrt cleared it right up and made this router into a decent piece of midrange equipment at rock bottom price.

Re: Wireless Router only works 'Wired'

I've been reading the forum and wondered why this was so common, especially with Linksys products, but with others as well. Is this a common failure mode, or is it just me? If it's as common as I've found it to be, is there a common failure point, or are there multiple issues with different routers?

For instance, I've had at least four Linksys routers, obtained from various sources, which failed to connect wirelessly, but which worked fine from the ethernet ports. Is Linksys unreliable, did I get bad ones (probable, considering my usual 'thrift store' acquisition technique), or is it just that they are so common that my scrounging finds them most often? Conversely, I've seen a couple work flawlessly for years.

To reiterate; many routers I have obtained work 'wired' but will not connect via wifi. Almost always the router is visible on the air, and will apparently connect to a remote computer, but will not pass data. I've had professionals come in (as a favor) and in vain try everything possible to make a connection...cloning MAC addresses, different modes of connection, flashing BIOS etc.

Some have failed after working for a time, others were obtained used and probably didn't work when I got them; while others were defective--brand new--right out of the box...various brands and models, but most often Linksys (although I've never had a brand-new Linksys fail out of box).

If your wireless is failing the 1st thing to try is changing the channel in the router. Interference is most likely the cause of poor or very limited wireless connection. Do bear in mind that with most house holds now with wireless routers you will get some interference from their routers. I work a lot on installation of networks and the symptons you describe is nearly always resolved by ensuring you have the latest drivers for your wireless device and changing your routers default wireless channel.

Re: Wireless Router only works 'Wired'

Well, take one apart where the wifi doesn't work and post a clear focused pictures using the manage attachments button and please do not post inline.

Thank you. This was more a general discussion question than a direct call for help, although I will eventually do as you ask. It seems odd that I keep having the same symptom across a variety of routers. Right now, using a Belkin that has been reliable after a BIOS upgrade.

No reason to have two (the others were scrapped) defective Linksys routers--as well a couple other brands--laying around. Someone could probably use them. Thanks again.

Re: Wireless Router only works 'Wired'

My 1.5 year-old Linksys WRT54GL did this last week. Wired side okay and no wireless. Unplugged the router for 15 minutes and it cleared itself up. I have a set of Panasonic FC's waiting to be installed if it acts up again. It has crap caps in it, waiting for a good time to change them out.
